| '''Bellatrix''', also known by its [[Bayer designation]] '''Gamma Orionis''' (γ Ori, γ Orionis), is the third brightest [[star]] in the [[constellation]] [[Orion (constellation)|Orion]]. A second-magnitude star, it is [[list of brightest stars|the twenty-seventh brightest star]] in the night sky.
| |
| | |
| ==Observational history==
| |
| Since 1963, Bellatrix was included with a set of bright stars that astronomers employ as a luminosity standard. These are used for comparison with other stars to check for variability, and so by definition, the apparent magnitude of Bellatrix was set to 1.64. However, when an all-sky [[Photometry (astronomy)|photometry]] survey was carried out in 1988, this star was itself found to be variable. It ranges in apparent magnitude from 1.59 to 1.64.<ref name=ibvs4028_1/>
| |
| | |
| ==Properties==
| |
| [[File:1e9m comparison.png|thumb|left|From left to right, the stars Bellatrix, the Sun, and [[Algol|Algol B]]]]
| |
| Bellatrix is a massive star with about 8.4 times the [[solar mass|Sun's mass]]. It has an estimated age of approximately 20 million years;<ref name=apj736_2_89/> long enough for a star of this mass to consume the hydrogen at its core and begin to evolve away from the [[main sequence]] into a [[giant star]].<ref name=kaler/> The [[effective temperature]] of the outer envelope of this star is 22,000 K,<ref name=aaa515_A74/> which is considerably hotter than the 5,778 K on the Sun. This high temperature gives this star the blue-white hue that occurs with [[B-type star]]s.<ref name=csiro/> The measured [[angular diameter]] of this star, after correction for [[limb darkening]], is {{nowrap|0.72 ± 0.04 [[milliarcsecond|mas]]}}.<ref name=aaa431_773/> At an estimated distance of {{Convert|250|ly|pc|abbr=off|lk=on}},<ref name=aaa474_2_653/> this yields a physical size of about six times the [[Solar radius|radius of the Sun]].<ref name=lang2006/><ref name=kaler/>
| |
| | |
| Bellatrix was once thought to belong to the [[Orion OB1 Association]] of stars that share a common motion through space, along with the "Orion's Belt" stars [[Zeta Orionis|ζ Ori]] (Alnitak), [[Epsilon Orionis|ε Ori]] (Alnilam), and [[Delta Orionis|δ Ori]] (Mintaka). However, this is no longer believed to be the case, as Bellatrix is now known to be much closer than the rest of the group.<ref name=kaler/> It is not known to have a stellar companion,<ref name=mnras389_2_869/> although researchers Maria-Fernanda Nieva and Norbert Przybilla raised the possibility it might be a spectroscopic binary composed of two very similar stars after detailed analysis of its spectrum, adding that this would explain its unexpected brightness.<ref>{{cite journal|last=Nieva, Maria-Fernanda; Przybilla, Norbert |date=2012|title=Present-day cosmic abundances. A comprehensive study of nearby early B-type stars and implications for stellar and Galactic evolution and interstellar dust models|journal=Astronomy & Astrophysics|volume=539A|pages=143-63|url=http://arxiv.org/pdf/1203.5787v2.pdf}}</ref> A 2011 search for nearby companions failed to conclusively find any objects that share a [[proper motion]] with Bellatrix. Three nearby candidates were all found to be background stars.<ref name=apj736_2_89/>

| | |
| ==Etymology and cultural significance==
| |
| The name ''Bellatrix'' is [[Latin]] for "female warrior", and first appeared in the works of [[Abu Ma'shar al-Balkhi]] and [[John of Seville]]. The name originally referred to Capella, but was transferred to Gamma Orionis by the Vienna school of astronomers in the 15th century, and appeared in contemporary reprints of the ''[[Alfonsine tables]]''.<ref name=Kunitzsch86>{{cite journal|last=Kunitzsch|first=Paul|year=1986|title=The Star Catalogue Commonly Appended to the Alfonsine Tables|journal=Journal for the History of Astronomy|volume=17|issue=49|pages=89–98|url=http://adsabs.harvard.edu/full/1986JHA....17...89K|bibcode = 1986JHA....17...89K }}</ref> It was also called the [[Amazons|Amazon Star]], which Richard Hinckley Allen proposed came from a loose translation of the Arabic name ''Al Najīd'', the Conqueror.<ref name=allen1963/> A c.1275 Arabic celestial globe records the name as المرزم "the lion".<ref>{{cite doi|10.1017/S0950473700000513}}</ref> Bellatrix is one of the four [[navigational stars]] in Orion that are used for [[celestial navigation]].<ref name=bennett2011/> The [[Chinese language|Chinese]] name for the star is 参宿五 ("''The Fifth of the Three Stars''").

| | |
| In the 17th century catalogue of stars in the ''Calendarium'' of [[Al Achsasi al Mouakket]], this star was designated ''Menkib al Jauza al Aisr'', which was translated into [[Latin]] as ''Humerus Sinister Gigantis''.<ref>{{cite journal

| [[J.K. Rowling]] named one of the Death Eaters "Bellatrix Lestrange". The Latin translation alludes to the character's nature in the [[Harry Potter]] series.

| | |
| The marooned astronauts in the original 1968 film of [[Planet of the Apes (1968 film)|Planet of the Apes]] initially believe that they are on an unknown planet orbiting Bellatrix, before the sole survivor realizes their true location in the final scene.
| |
| | |
| The [[Wardaman people]] of northern Australia know Bellatrix as ''Banjan'', the sparkling pigment used in ceremonies conducted by Rigel the Red Kangaroo Leader in a songline when Orion is high in the sky. The other stars of Orion are his ceremonial tools and entourage. Betelgeuse is ''Ya-jungin'' "Owl Eyes Flicking", watching the ceremonies.<ref>{{cite book | last1 = Harney | first1 = Bill Yidumduma

| To the Inuit, the appearance of Betelgeuse and Bellatrix high in the southern sky after sunset marked the beginning of spring and lengthening days in late February and early March. The two stars were known as ''Akuttujuuk'' "those (two) placed far apart", referring to the distance between them, mainly to people from North Baffin Island and Melville Peninsula.<ref name=inuit>{{cite book |title = The Arctic sky: Inuit astronomy, star lore, and legend |last = MacDonald |first = John |publisher = Royal Ontario Museum/Nunavut Research Institute|location=Toronto, Ontario/Iqaluit, NWT |year = 1998 |isbn = 9780888544278|pages=52–54, 119}}</ref>
