Carina (Chinese Astronomy)
The modern constellation Carina lies across one of the quadrants symbolized by the Vermillion Bird of the South (南方朱雀, ''Nán Fāng Zhū Què'') and The Southern Asterisms (近南極星區, ''Jìnnánjíxīngōu''), that divide the sky in traditional Chinese uranography. According to the quadrant, possibly constellation Carina in Chinese sky is almost not seen, except Canopus (Alpha Carinae), and Canopus is "south pole" in Chinese sky, and Miaplacidus (Beta Carinae), Aspidiske (Iota Carinae) and Avior (Epsilon Carinae) are bright stars in this constellation that are possibly never seen in the Chinese sky. The name of the western constellation in modern Chinese is 船底座 (''chuán dǐ zuò''), meaning "the bottom of boat constellation".

Carina (constellation)
Carina ( ) is a constellation in the southern sky. Its name is Latin for the keel of a ship, and it was the southern foundation of the larger constellation of Argo Navis (the ship ''Argo'') until it was divided into three pieces, the other two being Puppis (the poop deck), and Vela (the sails of the ship). History and mythology Carina was once a part of Argo Navis, the great ship of Jason and the Argonauts who searched for the Golden Fleece. The constellation of Argo was introduced in ancient Greece. However, due to the massive size of Argo Navis and the sheer number of stars that required separate designation, Nicolas-Louis de Lacaille divided Argo into three sections in 1763, including Carina (the hull or keel). In the 19th century, these three became established as separate constellations, and were formally included in the list of 88 modern IAU constellations in 1930. Lacaille kept a single set of Greek letters for the whole of Argo, and separate sets of Latin letter designa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Brightest Stars
This is a list of stars arranged by their apparent magnitude – their brightness as observed from Earth. It includes all stars brighter than magnitude +2.50 in visible light, measured using a ''V''-band filter in the UBV photometric system. Stars in binary systems (or other multiples) are listed by their ''total'' or ''combined'' brightness if they appear as a single star to the naked eye, or listed separately if they do not. As with all magnitude systems in astronomy, the scale is logarithmic and inverted i.e. lower/more negative numbers are brighter. Most stars on this list appear bright from Earth because they are nearby, not because they are intrinsically luminous. For a list which compensates for the distances, converting the ''apparent'' magnitude to the ''absolute'' magnitude, see the list of most luminous stars. Measurement The Sun is the brightest star as viewed from Earth, at −26.74 mag. The second brightest is Sirius at −1.46 mag. For c ...

Omega Carinae
Omega Carinae, Latinized from ω Carinae, is a star in the constellation Carina. With a declination greater than 70 degrees south of the celestial equator, it is the most southerly of the bright stars of Carina (third-magnitude or brighter), and it is part of a southern asterism known as the Diamond Cross. This star has an apparent visual magnitude of 3.3 and is located at a distance of about from Earth. Properties Omega Carinae has a stellar classification of B8 IIIe, which places it in the category of Be stars, that display emission lines of hydrogen their spectrum. Omega Carinae is a shell star, having a circumstellar disk of gas surrounding its equator. The luminosity class of III indicates it has evolved into a giant star, having exhausted the hydrogen at its core and left the main sequence. The effective temperature of in its outer envelope is what gives this star the blue-white hue that is characteristic of B-type stars. This star is rotating rapidly ...

Theta Carinae
θ Carinae, Latinized as Theta Carinae, is a spectroscopic binary star in the southern constellation of Carina. With an apparent visual magnitude of 2.76, it is the brightest star in the open star cluster IC 2602. It marks the northeastern end of the Diamond Cross asterism. Parallax measurements from the Hipparcos mission place this star at a distance of about from Earth. Properties The MKK stellar classification of this star is B0.5 Vp, which indicates this B-type main sequence star generates energy through the nuclear fusion of hydrogen in its core. The 'p' suffix designates peculiar spectral features, which have been observed in both optical and ultraviolet wavelengths. Theta Carinae is a single-lined spectroscopic binary with a 2.2 day period; the shortest known orbital period among massive stars, suggesting earlier mass transfer between the two components, possibly explaining the spectral peculiarities. In this spectroscopic system, the primary star i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PP Carinae
p Carinae is the Bayer designation of a star in the southern constellation of Carina. It has the variable star designation PP Carinae and, at an apparent visual magnitude of +3.3, is readily visible to the naked eye from the southern hemisphere. From the observed parallax shift of this star as the Earth orbits the Sun, its distance can be estimated as roughly with a 6% margin of error. It is considered to be a member of the open cluster IC 2602 although it lies well outside the core visible group of stars. The star is a B-type main sequence star with a stellar classification of B4 Vne. The 'ne' suffix indicates it is a rapidly rotating Be star that is surrounded by hot circumstellar gas. This material adds emission lines to the spectrum of the star. It has a projected rotational velocity of , with about 7.6 times the mass and 6 times the radius of the Sun. This star is classified as a Gamma Cassiopeiae-type variable and its brightness varies from magnitude +3.22 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

V382 Carinae
V382 Carinae, also known as x Carinae (x Car), is a yellow hypergiant in the constellation Carina. It is a G-type star with a mean apparent magnitude of +3.93, and a variable star of low amplitude. Variability The radial velocity of V382 Carinae has long been known to be variable, but variations in its brightness were unclear. Brightness variations were detected by some observers, but others found it to be constant. It was formally named as a variable star in 1981, listed in the General Catalogue of Variable Stars as a possible δ Cephei variable. It has been described as a ''pseudo-Cepheid'', a supergiant with pulsations similar to a Cepheid but less regular. Analysis of Hipparcos photometry showed clear variation with a maximum range of 0.12 magnitudes and the star was treated as an α Cygni variable. A period of 556 days was suggested, but it is not entirely consistent. It is now generally treated as a semiregular or irregular supergiant. Properties V3 ...
