Phoenix (Chinese Astronomy)
The modern constellation Phoenix lies across one of the quadrants symbolized by the White Tiger of the West (西方白虎, ''Xī Fāng Bái Hǔ''), and The Southern Asterisms (近南極星區, ''Jìnnánjíxīngōu''), that divide the sky in traditional Chinese uranography. According to the quadrant, constellation Phoenix in Chinese sky is not fully seen. Ankaa (Alpha Phoenicis) are bright stars in this constellation that possibly never seen in Chinese sky. The name of the western constellation in modern Chinese is 鳳凰座 (''fèng huáng zuò''), which means "the phoenix constellation".

Phoenix (constellation)
Phoenix is a minor constellation in the southern sky. Named after the mythical phoenix, it was first depicted on a celestial atlas by Johann Bayer in his 1603 ''Uranometria''. The French explorer and astronomer Nicolas Louis de Lacaille charted the brighter stars and gave their Bayer designations in 1756. The constellation stretches from roughly −39° to −57° declination, and from 23.5h to 2.5h of right ascension. The constellations Phoenix, Grus, Pavo and Tucana, are known as the Southern Birds. The brightest star, Alpha Phoenicis, is named Ankaa, an Arabic word meaning 'the Phoenix'. It is an orange giant of apparent magnitude 2.4. Next is Beta Phoenicis, actually a binary system composed of two yellow giants with a combined apparent magnitude of 3.3. Nu Phoenicis has a dust disk, while the constellation has ten star systems with known planets and the recently discovered galaxy clusters El Gordo and the Phoenix Cluster—located 7.2 and 5.7 billion light years away ...

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 ...

Zeta Phoenicis
Zeta Phoenicis (ζ Phoenicis, abbreviated Zet Phe, ζ Phe) is a multiple star system in the constellation of Phoenix. It is visible to the naked eye. Based upon parallax measurements made by the Hipparcos spacecraft, it is located some away. Zeta Phoenicis A is itself an Algol-type eclipsing binary star. It consists of two B-type main sequence stars that orbit each other. The larger and brighter (Zeta Phoenicis Aa) is formally named Wurren . When one passes in front of one another, it blocks some of the other star's light. As a result, its apparent magnitude fluctuates between 3.9 and 4.4 with a period of 1.6697739 days (its orbital period). The system most likely contains four stars with two other telescopic components of apparent magnitude 7.2 and 8.2 at angular separations of 0.8 and 6.4 arcseconds from the main pair. The closer (Zeta Phoenicis B) is an A-type main-sequence star with an orbital period around the main pair of about 210 years, as well as an eccentric ...

HD 222095
HD 222095 is a single star in the southern constellation of Phoenix, near the western constellation border with Grus. It has a white hue and is visible to the naked eye with an apparent visual magnitude of 4.74. The star is located at a distance of is approximately 200 light years based on parallax, and it is drifting further away with a radial velocity of +3.4 km/s. This object is an A-type main-sequence star with a stellar classification of A1/2V. It has a high rate of spin with a projected rotational velocity of 141 to 165 km/s, giving it an equatorial bulge that is 4% larger than the polar radius. The star is 482 million years old with 2.55 times the mass of the Sun and around 2.2 times the Sun's radius. It is radiating 41 times the luminosity of the Sun from its photosphere at an effective temperature The effective temperature of a body such as a star or planet is the temperature of a black body that would emit the same total amount of electroma ...

Gamma Phoenicis
Gamma Phoenicis is a star system in the constellation Phoenix, located around distant. γ Phoenicis is a spectroscopic binary and a small amplitude variable star. The star system shows regular variations in brightness that were reported as a 97.5 day period in the Hipparcos catalogue, but have since been ascribed to a 194.1-day orbital period with primary and secondary minima. Although the light curve appears to show eclipses, the high orbital inclination suggests the variations are due to ellipsoidal stars as they rotate in their orbit. γ Phoenicis is listed in the General Catalogue of Variable Stars as a possible slow irregular variable with a range from 3.39 to 3.49, the same as reported for the eclipses or ellipsoidal variations. Only the primary star in the γ Phoenicis system is visible. The second is inferred solely from variations in the radial velocity of the primary star. The primary is a red giant of spectral type M0III, a star that has used up it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beta Phoenicis
Beta Phoenicis (β Phoenicis, β Phe) is a binary star in the constellation Phoenix. Its apparent magnitude is 3.30, meaning that it can be seen with the naked eye ''(see Bortle scale)''. The distance to Beta Phoenicis is poorly known. The original reduction of the Hipparcos satellite's data yielded a parallax value of 16 milliarcseconds, yet its standard error was larger than the parallax value itself. The new reduction of the Hipparcos data gave 0.12 ± 14.62 milliarcseconds, still unusable. The General Catalogue of Trigonometric Parallaxes, an older catalogue of ground-based parallaxes, lists the parallax as 20 ± 16 milliarcseconds, corresponding to about . Beta Phoenicis is a relatively wide visual binary consisting of two G-type giant stars, both with spectral type In astronomy, stellar classification is the classification of stars based on their spectral characteristics.

White Tiger (Chinese Constellation)
The White Tiger (Chinese: 白虎, Pinyin: ''Báihǔ''), known in Chinese as Baihu, is one of the Four Symbols of the Chinese constellations. It is sometimes called the White Tiger of the West (). It represents the west in terms of direction and the autumn season. It is known as Byakko in Japanese, Baekho in Korean, and Bạch Hổ in Vietnamese. Seven Mansions As with the other three Symbols, there are seven astrological "Mansions" (positions of the Moon) within the White Tiger. The names and determinative stars are: Origin In Chinese culture, the tiger is the king of the beasts and has been presented with a () on his forehead for centuries. According to legend, the tiger's tail would turn white when it reached the age of 500 years. In this way, the white tiger became a kind of mythological creature. It was said that the white tiger would only appear when the emperor ruled with absolute virtue or if there was peace throughout the world. Because the color white of the Wu Xing ...
