Lepus (Chinese Astronomy)
According to traditional Chinese uranography, the modern constellation Lepus is located within the western quadrant of the sky, which is symbolized as The White Tiger of the West (西方白虎, ''Xī Fāng Bái Hǔ'') The name of the western constellation in modern Chinese is 天兔座 (''tiān tù zuò''), meaning "the celestial rabbit constellation".

Traditional Chinese Star Names
Chinese star names ( Chinese: , ''xīng míng'') are named according to ancient Chinese astronomy and astrology. The sky is divided into star mansions (, ''xīng xiù'', also translated as "lodges") and asterisms (, ''xīng guān''). The system of 283 asterisms under Three Enclosures and Twenty-eight Mansions was established by Chen Zhuo of the Three Kingdoms period, who synthesized ancient constellations and the asterisms created by early astronomers Shi Shen, Gan De and Wuxian. Since the Han and Jin Dynasties, stars have been given reference numbers within their asterisms in a system similar to the Bayer or Flamsteed designations, so that individual stars can be identified. For example, Deneb (α Cyg) is referred to as (''Tiān Jīn Sì'', the Fourth Star of Celestial Ford). In the Qing Dynasty, Chinese knowledge of the sky was improved by the arrival of European star charts.

Lambda Leporis
Lambda Leporis, which is the Latinized form of λ Leporis, is a solitary, blue-white hued star in the southern constellation of Lepus. It is visible to the naked eye with an apparent visual magnitude of +4.29. Based upon an annual parallax shift of 3.83 mas, it is estimated to lie roughly 850 light years from the Sun. Relative to its neighbors, this star has a peculiar velocity of . It is a member of the Orion OB1 association (Ori OB1), and it has been identified as a high-velocity runaway star.

Chinese Constellations
Traditional Chinese astronomy has a system of dividing the celestial sphere into asterisms or constellations, known as "officials" (Chinese ''xīng guān''). The Chinese asterisms are generally smaller than the constellations of Hellenistic tradition. The Song dynasty (13th-century) Suzhou planisphere shows a total of 283 asterisms, comprising a total of 1,565 individual stars. The asterisms are divided into four groups, the Twenty-Eight Mansions (, ''Èrshíbā Xiù'') along the ecliptic, and the Three Enclosures of the northern sky. The southern sky was added as a fifth group in the late Ming Dynasty based on European star charts, comprising an additional 23 asterisms. The Three Enclosures (, ''Sān Yuán'') include the Purple Forbidden Enclosure, which is centered on the north celestial pole and includes those stars which could be seen year-round,Needham, J.Astronomy in Ancient and Medieval China.

Delta Leporis
Delta Leporis (δ Leporis) is a solitary, orange-hued star in the southern constellation of Lepus. It is visible to the naked eye with an apparent visual magnitude of 3.85. Based upon an annual parallax shift of 28.68 mas, it is 114 light years distant from Earth. This is an old, evolved K-type star with an age of about 10.7 billion years. Keenan and McNeil (1989) classified it as , indicating it is a giant star showing a deficiency of iron and an excess of cyanogen in its atmosphere. However, Gray et al. (2006) listed it as , which would suggest a less evolved subgiant star. It may be a red clump star, which indicates it is generating energy through helium fusion at its core. The measured angular diameter of this star, after correction for limb darkening, is . At the estimated distance of this star, this yields a physical size of about 10 times the radius of the Sun. It has only 94% of the Sun's mass and is radiating 46 times the Sun's luminosity from its photo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gamma Leporis, Latinized from γ Leporis, is a star in the south central part of the constellation Lepus, southeast of Beta Leporis and southwest of Delta Leporis. With an apparent visual magnitude of 3.587, it is bright enough to be seen with the naked eye. Based upon an annual parallax shift of as seen from Earth, its distance can be estimated as 29 light years from the Sun. It has a common proper motion companion, AK Leporis, which is a variable star of the BY Draconis type and has an average brightness of magnitude 6.28. The two are apart can be well seen in binoculars. Gamma Leporis is a member of the Ursa Major Moving Group. Gamma Leporis is an F-type main-sequence star with a stellar classification of F6 V. It is larger than the Sun with 1.2 times the radius of the Sun and 1.3 times the Sun's mass. The star is around 1.3 billion years old and is spinning with a rotation period of about six days.

Beta Leporis
Beta Leporis (β Leporis, abbreviated Beta Lep, β Lep), formally named Nihal , is the second brightest star in the constellation of Lepus. Nomenclature ''Beta Leporis'' is the star's Bayer designation. It is also known by the traditional named ''Nihal'', Arabic for "quenching their thirst". The occasional spelling ''Nibal'' appears to be due to a misreading. In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. The WGSN's first bulletin of July 2016 included a table of the first two batches of names approved by the WGSN; which included ''Nihal'' for this star. In Chinese, (), meaning ''Toilet'', refers to an asterism consisting of β Leporis, α Leporis, γ Leporis and δ Leporis. Consequently, the Chinese name for β Leporis itself is (), "the Second Star of Toilet". [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpha Leporis
Alpha Leporis (α Leporis, abbreviated Alpha Lep, α Lep), formally named Arneb , is the brightest star in the constellation of Lepus. Nomenclature ''Alpha Leporis'' is the star's Bayer designation. The traditional name ''Arneb'' comes from the Arabic ''أرنب'' ''’arnab'' 'hare' ('Lepus' is Latin for hare). In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. The WGSN's first bulletin of July 2016 included a table of the first two batches of names approved by the WGSN; which included ''Arneb'' for this star. In Chinese, (), meaning ''Toilet'', refers to an asterism consisting of α Leporis, β Leporis, γ Leporis and δ Leporis. Consequently, the Chinese name for α Leporis itself is (), "the First Star of Toilet". [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nu Leporis
Nu Leporis, Latinized from ν Leporis, is a probable astrometric binary star system in the constellation Lepus. It is visible to the naked eye as a faint star with an apparent visual magnitude of 5.29. Based upon an annual parallax shift of 7.70 mas as seen from the Earth, it is 420 light years from the Sun. The visible component is a B-type star with an estimated 3.3 times the mass of the Sun. Lesh (1968) gave a stellar classification of B7 IVnn, which would indicate this is a somewhat evolved subgiant star. The 'nn' notation indicates especially "nebulous" absorption lines caused by rapid rotation. Houk and Smith-Moore (1978) listed it as B7/8 V, suggesting this is instead a B-type main sequence star that has not yet consumed all the hydrogen at its core. Nu Leporis is spinning rapidly with a projected rotational velocity of 285 km/s. The star has a radius about three times that of the Sun and is radiating 138 times the Sun's luminosity from its ...

Lepus (constellation)
Lepus (, ) is a constellation lying just south of the celestial equator. Its name is Latin for hare. It is located below—immediately south—of Orion (the hunter), and is sometimes represented as a hare being chased by Orion or by Orion's hunting dogs. Although the hare does not represent any particular figure in Greek mythology, Lepus was one of the 48 constellations listed by the 2nd-century astronomer Ptolemy, and it remains one of the 88 modern constellations. History and mythology Lepus is most often represented as a hare being hunted by Orion, whose hunting dogs (Canis Major and Canis Minor) pursue it. The constellation is also associated with the Moon rabbit. Four stars of this constellation (α, β, γ, δ Lep) form a quadrilateral and are known as ''‘Arsh al- Jawzā''', "the Throne of Jawzā'" or ''Kursiyy al-Jawzā' al-Mu'akhkhar'', "the Hindmost Chair of Jawzā'" and ''al-Nihāl'', "the Camels Quenching Their Thirst" in Arabic.
