[61] This visual companion is designated as component C (Rigel C), with a measured separation from component B that varies from less than 0.1″ to around 0.3″. The Rigel rocket has a maximum altitude of 310 km, a launch mass of 300 kg, a … I stumbled upon a book about the fixed stars and it referenced two stars that give positive results, Rigel and Spica stars of Fortune by DM Hoover. Rigel is the star that indicates great wealth. [86][87][88] The SSM-N-6 Rigel was a cruise missile program for the US Navy that was cancelled in 1953 before reaching deployment. Rigel's name is popular in science-fiction. Visit our corporate site. As such, their characteristics are mainly estimated from theoretical stellar evolution models. Thank you for signing up to Space. Rigel (sometimes called Rigel A to distinguish from the other components) has a visual companion, which is likely a close triple-star system. [9], Rigel's distance from the Sun is somewhat uncertain, different estimates being obtained by different methods. [24] In the Southern Hemisphere, Rigel is the first bright star of Orion visible as the constellation rises. Get breaking space news and the latest updates on rocket launches, skywatching events and more! Calculations of mass loss from the Hγ line give (9.4±0.9)×10−7 M☉/yr in 2006-7 and (7.6±1.1)×10−7 M☉/yr in 2009–10. Rigl means foot and Jauzah means Orion. [11], The earliest known recording of the name Rigel is in the Alfonsine tables of 1521. [8][61] In 2009, speckle interferometry showed the two almost identical components separated by 0.124″,[62] with visual magnitudes of 7.5 and 7.6, respectively. [79] Its heliacal rising presages the appearance of Matariki (the Pleiades) in the dawn sky, marking the Māori New Year in late May or early June. [21] A spectroscopic companion to Rigel was reported on the basis of radial velocity variations, and its orbit was even calculated, but subsequent work suggests the star does not exist and that observed pulsations are intrinsic to Rigel itself. [8] Gaia DR2 finds it to be a 12th magnitude sunlike star at approximately the same distance as Rigel. the brightest star, Beta Orionis, in the constellation Orion: a very luminous and extremely remote bluish-white supergiant, a double star. 28° Gemini 58: Betelgeuse – Gotta love the name. Fate. "The blue color of the Witch Head Nebula and of the dust surrounding Rigel is caused not only by Rigel's intense blue starlight, but because the dust grains scatter blue light more efficiently than red," NASA wrote. Rigel lies 778 light-years from Earth in Orion. Meanings and history of the name Rigel. Rigel is surrounded by a shell of expelled gas. [57][58] The secondary star is often referred to as Rigel B or β Orionis B. Further observations of radial velocity variations indicate that it simultaneously oscillates in at least 19 non-radial modes with periods ranging from about 1.2 to 74 days. Due to its brightness and its recognizable name, Rigel is also a popular fixture in science fiction. It is expected to end its life as a type II supernova, leaving a neutron star or a black hole as a final remnant, depending on the initial mass of the star. It is a variable star (its apparent brightness varies) and is considered an Alpha Cygni-type star. Rigel's color index varies slightly, but this is not significantly correlated with its brightness variations. In the Orion constellation, Rigel is the blue star of the first magnitude that marks the hunter's left foot. Rigel as a boys' name is pronounced RYE-jel. Betelgeuse is Ya-jungin "Owl Eyes Flicking", watching the ceremonies. [65], Rigel is expected to eventually end its stellar life as a type II supernova. This is the name of the star that forms the left foot of the constellation Orion. Along with Agena , it makes up the Pointer Stars to the Southern Cross, constellation Crux . Contrasting with the orange-red Betelgeuse, Rigel appears as blue-white to the naked eye. Astronomers have made several observations of Rigel in recent years. For us, the star represents the mythical Hunter's left foot, It is derived from the Arabic name Rijl Jauzah al Yusrā, "the left leg (foot) of Jauzah" (i.e. [27], Rigel has many other stellar designations taken from various catalogs, including the Flamsteed designation 19 Orionis (19 Ori), the Bright Star Catalogue entry HR 1713, and the Henry Draper Catalogue number HD 34085. The Washington Double Star Catalog", Astronomy and Astrophysics Supplement Series, "MSC – a catalogue of physical multiple stars", Monthly Notices of the Royal Astronomical Society, "Catalogue of Double Stars. Rigel definition: the brightest star , Beta Orionis, in the constellation Orion : a very luminous and... | Meaning, pronunciation, translations and examples [15], From observations of the variable Hα spectral line, Rigel's mass-loss rate due to stellar wind is estimated be (1.5±0.4)×10−7 solar masses per year (M☉/yr)—about ten million times more than the mass-loss rate from the Sun. [89], The Rigel Skerries are a chain of small islands in Antarctica, renamed after originally being called Utskjera. It was requisitioned by the Germans during World War II and sunk in 1944 while being used to transport prisoners of war. rijl meaning "leg, foot"),[70] which can be traced to the 10th century. Rarely, there is a pure emission Hα line. It is of Arabic origin, and the meaning of Rigel is "foot". [44], From analysis of Hipparcos satellite photometry, Rigel is identified as belonging to the Alpha Cygni class of variable stars,[45] defined as "non-radially pulsating supergiants of the Bep–AepIa spectral types". Jauzah was the Arabic name for the constellation Orion, representing a female figure whose identity is uncertain. The name comes from an Arabic phrase, "Rijl Jauzah al Yusrā," which means, "The left leg of the Jauzah," according to Richard Hinckley Allen's book "Star Names: Their Lore and Meaning" (Dover Publications, 2013). Due to its measured size and brightness it is expected to end in a supernova one day. RIGEL (Beta Orionis). Light from the star Rigel reflects off the dust composing the Witch Head Nebula. [8][59] Although not particularly faint at visual magnitude 6.7, the overall difference in brightness from Rigel A (about 6.6 magnitudes or 440 times fainter) makes it a challenging target for telescope apertures smaller than 15 cm (6 in). [73] In the Caribbean, Rigel represented the severed leg of the folkloric figure Trois Rois, himself represented by the three stars of Orion's Belt. [54][60] The pair would have an estimated orbital period of 24,000 years. [22][29], Rigel is an intrinsic variable star with an apparent magnitude ranging from 0.05 to 0.18. Video shows what Rigel means. The two spectroscopic components Rigel Ba and Rigel Bb cannot be resolved in optical telescopes but are known to both be hot stars of spectral type around B9. [33] Correspondingly it is also the first star of Orion to set in most of the Northern Hemisphere. Occasional very high-velocity outflows have been inferred, and, more rarely, infalling material. The terminal wind velocity is 300 km/s. Al-Sufi himself planned the figures, two for each constellation: one shows how they appear to an observer looking up toward the heavens; the other how they appear to the observer looking down upon a celestial globe. [47] Rigel was added to the General Catalogue of Variable Stars in the 74th name-list of variable stars on the basis of the Hipparcos photometry,[48] which showed variations with a photographic amplitude of 0.039 magnitudes and a possible period of 2.075 days. These pulsations are stronger and more numerous in stars that have evolved through a red supergiant phase and then increased in temperature to again become a blue supergiant. Rigel is a blue supergiant that is the brightest star in the constellation Orion (the Hunter). Rigel is more properly (to astronomers) known as Beta Orionis. [14][39], As early as 1888, the heliocentric radial velocity of Rigel, as estimated from the Doppler shifts of its spectral lines, was seen to vary. It is a member of the loosely defined Taurus-Orion R1 Association, somewhat closer at 1,200 light-years (360 parsecs). Classified under: Nouns denoting natural objects (not man-made) Synonyms: Beta Orionis; Rigel. Rigel is the brightest star in the constellation Orion. 9° Gemini 59: Aldebaran – A Royal Star. The color of this star is bluish-white, hotter than a star with a yellow color, meaning it will use more energy quickly. [80] Puaka is a southern name variant used in the South Island. They were given their current name as Rigel was used as an astrofix. For example, a 2014 study examined the variability of stellar winds coming from Rigel over several years. Fixed star Rigel, Beta Orionis, is a 0.1 magnitude bluish triple star system situated on the left foot of the Hunter, Orion Constellation. This is the name of the star that forms the left foot of the … And, a 2017 study measured the stellar flux density of Rigel and two other stars, Aldebaran and Fomalhaut. [12], Stellar evolution models suggest the pulsations of Rigel are powered by nuclear reactions in a hydrogen-burning shell that is at least partially non-convective. The double stage Rigel (first stage Canopus 1, second stage Orion-2) was launched seven times between 1969 and 1973. Rigel, also called Beta Orionis, one of the brightest stars in the sky, intrinsically as well as in appearance. Rigel Kent is the romanization of the Arabic Rijl Qanṭūris, meaning “the foot of the Centaur”. The inner stars of the triple system orbit each other every 10 days, and the outer star orbits the inner pair every 63 years. The Gaia DR2 proper motions for Rigel B and the Hipparcos proper motions for Rigel are both small, although not quite the same. These three stars are all blue-white main sequence stars, each three to four times as massive as the Sun. The name Rigel derives from an Arabic term meaning “the left leg of the giant,” referring to the figure of … rijl meaning "leg, foot"), which can be traced to the 10th century. ... Rigel (noun) a fixed star of the first magnitude in the left foot of the constellation Orion. Rigel varies slightly in brightness, its apparent magnitude ranging from 0.05 to 0.18. [35][36] The overall spectrum is typical for a late B class star, with strong absorption lines of the hydrogen Balmer series as well as neutral helium lines and some of heavier elements such as oxygen, calcium, and magnesium. ", CDS/ADC Collection of Electronic Catalogues, "Times-Series Photometry & Spectroscopy of the Bright Blue Supergiant Rigel: Probing the Atmosphere and Interior of a SN II Progenitor", Proceedings of the International Astronomical Union, "The 2001 US Naval Observatory Double Star CD-ROM. [75], Rigel was known as Yerrerdet-kurrk to the Wotjobaluk koori of southeastern Australia, and held to be the mother-in-law of Totyerguil (Altair). [76] The indigenous Boorong people of northwestern Victoria named Rigel as Collowgullouric Warepil. [9], Although Rigel is often considered the most luminous star within 1,000 light-years of the Sun,[24][29] its energy output is poorly known. [Full story], NASA's Astronomy Picture of the Day website, Proceedings of the International Astronomical Union, On This Day in Space! The Star Rigel is influencing your fate. [30] Rigel appears slightly blue-white and has a B-V color index of −0.06. Rigel is a prominent equatorial navigation star, being easily located and readily visible in all the world's oceans (the exception is the area north of the 82nd parallel north). Rigel is a variable star, thus it is occasionally outshone by Betelgeuse. It's in the name of a number of planets in the "Star Trek" universe, is mentioned in "The Hitchhiker's Guide to the Galaxy," and is also featured in a number of other novels, computer games and comic books. Rigel is a massive blue supergiant with a luminosity of around 61.500 up to 363.000 that of the Sun. [55], Rigel is an outlying member of the Orion OB1 Association, which is located at a distance of up to 1,600 light-years (500 parsecs) from Earth. [30] In those spectral types, the 'e' indicates that it displays emission lines in its spectrum, while the 'p' means it has an unspecified spectral peculiarity. [52], In 1871, Sherburne Wesley Burnham suspected Rigel B to be a binary system, and in 1878, he resolved it into two components. [8], Component B is a double-lined spectroscopic binary system, which shows two sets of spectral lines combined within its single stellar spectrum. I. Rigelians were believed to have four or five genders, according to information obtained by Doctor Phlox. [43], Rigel has been known to vary in brightness since at least 1930. [70], With the constellation representing the mythological Greek huntsman Orion, Rigel is his knee or (as its name suggests) foot; with the nearby star Beta Eridani marking Orion's footstool. You will receive a verification email shortly. (ENT [41], In 1933, the Hα line in Rigel's spectrum was seen to be unusually weak and shifted 0.1 nm towards shorter wavelengths, while there was a narrow emission spike about 1.5 nm to the long wavelength side of the main absorption line. Since its discovery, there has been no sign of orbital motion, although both stars share a similar common proper motion. [3] Rigel B, usually considered to be physically associated with Rigel and at the same distance, has a Gaia Data Release 2 parallax of 2.9186±0.0761 mas, suggesting a distance around 1,100 light-years (340 parsecs).

[67] A 2018 study using the Navy Precision Optical Interferometer measured the angular diameter as 2.526 mas. The name Rigel (pronunciation: /ˈraɪdʒəl/) comes from the Arabic phrase Rijl Jauzah al Yusrā, meaning “the left leg of the central one,” and refers to the star’s position at the foot or leg of Orion. )[5] The supernova would leave behind either a black hole or a neutron star. Al-Sufi's book was translated into Latin and other European languages. ABSOLUTE AND APPARENT MAGNITUDE: Apparent magnitude: 0.18v Absolute magnitude: -6.69 OTHER INTERESTING INFORMATION: Rigel is the brightest star in the constellation Orion and the seventh brightest star in the night sky [34], Rigel's spectral type is a defining point of the classification sequence for supergiants. The two powerful families fought the Genpei War; the stars were seen as facing off against each other and kept apart only by the three stars of Orion's Belt. [11] Due to strong convection of helium produced in the core while Rigel was on the main sequence and in the hydrogen-burning shell since it became a supergiant, the fraction of helium at the surface has increased from 26.6% when the star formed to 32% now. Its name comes from the same root as Betelgeuse's, originally "rijl al-jauza," meaning the "foot" of al-jauza, the Arab's "Central One." [32], Culminating every year at midnight on 12 December, and at 9:00 pm on 24 January, Rigel is visible on winter evenings in the Northern Hemisphere and on summer evenings in the Southern Hemisphere. [12] Gaia Data Release 2 (DR2) contains a somewhat unreliable parallax for Rigel B, placing it at about 1,100 light-years (340 parsecs), further away than the Hipparcos distance for Rigel, but similar to the Taurus-Orion R1 association. The name “Orion” means “He who comes forth as light.” This appellation can apply to Christ in His role as Messiah. For simplicity, Rigel's companions are referred to as Rigel B,[20] C, and D;[21][22] the IAU describes such names as "useful nicknames" that are "unofficial". Find Rigel multiple name meanings and name pronunciation in English, Arabic and Urdu. Rigel is a Muslim Boy name and has Arabic origin. [9] Other calculations based on theoretical stellar evolutionary models of Rigel's atmosphere give luminosities anywhere between 83,000 L☉ and 363,000 L☉,[28] while summing the spectral energy distribution from historical photometry with the Hipparcos distance suggests a luminosity as low as 61,515±11,486 L☉. In general, the group found that stellar flux density is at a minimum at the outer surface of a star and at a maximum inside of the star. [51], Due to their closeness to each other and ambiguity of the spectrum, little is known about the intrinsic properties of the members of the Rigel BC triple system. [21] From measures of other nebula-embedded stars, IC 2118's distance is estimated to be 949 ± 7 light-years (291 ± 2 parsecs). It has been a known visual binary since 1831, possibly even earlier, when F. G. Struve first measured it. [42], The unusual Hα line profile is observed to vary unpredictably. Rigel is really a star system composed of three stars. [20] In modern comprehensive catalogs, the whole multiple star system is known as WDS 05145-0812 or CCDM 05145–0812. Artist's impression of the blue giant Rigel, one of the brightest stars in the night sky. © This was confirmed and interpreted at the time as being due to a spectroscopic companion with a period of about 22 days. Fixed star Rigel Tropical degree of Rigel: 16 degrees 49 minutes Gemini Sidereal degree of Rigel: 23 Degrees Taurus According to Ptolemy and Lilly… Analysis of the Hα and Hγ line profiles, and measurement of the regions producing the lines, show that Rigel's stellar wind varies greatly in structure and strength. The surface abundances of carbon, nitrogen, and oxygen seen in the spectrum are compatible with a post-red supergiant star only if its internal convection zones are modeled using non-homogeneous chemical conditions known as the Ledoux Criteria. Instance hypernyms: The modern name Rigel and traditional name Jauzah both come from the Arabic phrase Rijl Jauzah al Yusrā which means the left leg (foot) of Jauzah. This is one of the wealth stars, so it can bring you big material attainments. Freebase (0.00 / 0 votes) Rate this definition: Rigel. "Jauzah" was a proper name for Orion; an alternative Arabic name was رجل الجبار rijl al-jabbār, "the foot of the great one", from which stems the rarely used variant names Algebar or Elgebar. Rigel is also a multiple star system – composed of at least four stars. This spectroscopic binary, together with the close visual component Rigel C, is likely a physical triple-star system,[60] although Rigel C cannot be detected in the spectrum, which is inconsistent with its observed brightness. Derived from Arabic الرجل (al-Rijl) meaning "foot". [67] An older measurement of the angular diameter gives 2.75±0.01 mas,[68] equivalent to a radius of 78.9 R☉ at 264 pc. Rigel Name Meaning is Foot, Rigel Is A Blue Star Of The First Magnitude That Marks The Hunter's Left Foot In The Orion Constellation. Rigel's bright starlight also bounces off a nearby nebula, as shown in a picture published in 2012 on NASA's Astronomy Picture of the Day website. Derived from Arabic الرجل (al-Rijl) meaning "foot", it forms the left foot of the constellation. A [28][56] Rigel is thought to be considerably closer than most of the members of Orion OB1 and the Orion Nebula. And if you have a news tip, correction or comment, let us know at: community@space.com. A star in Orion’s foot also marks this constellation as a representation of the Messiah to Come, the Desired of All Nations (Haggai 2:7). Join our Space Forums to keep talking space on the latest missions, night sky and more! [39], Hierarchical scheme for Rigel's components[12]. With an estimated age of seven to nine million years, Rigel has exhausted its core hydrogen fuel, expanded, and cooled to become a supergiant. Rigel definition: the brightest star , Beta Orionis, in the constellation Orion : a very luminous and... | Meaning, pronunciation, translations and examples [78], The Māori people of New Zealand named Rigel as Puanga, said to be a daughter of Rehua (Antares), the chief of all-stars. The Rigel star system has evolved off the main sequence, and some investigators estimate that it has lost as much as 3 solar masses of material during its short life of only 7 to 9 million years. A person who is good at practically everything he tries. Eridanus, the river, marks a line of stars in the sky leading to it, and the other stars of Orion are his ceremonial tools and entourage. Due to its measured size and brightness it is expected to end in a supernova one day. Milli-magnitude variations were observed, and gradual changes in flux suggest the presence of long-period pulsation modes. Rigel is close to zero magnitude in Earth's sky, making it a bright star, and is best visible in the winter northern sky. Observations over 18 nights in 1984 showed variations at red, blue, and yellow wavelengths of up to 0.13 magnitudes on timescales of a few hours to several days, but again no clear period. Dictionary of Nautical Terms (0.00 / 0 votes) Rate this definition: rigel. A blue supergiant star in the constellation Orion; Beta (β) Orionis. [11] It is one of the closest known potential supernova progenitors to Earth,[15] and would be expected to have a maximum apparent magnitude of around −11 (about the same brightness as a quarter Moon or around 300 times brighter than Venus ever gets.
