Cygnus In Chinese Astronomy
According to traditional Traditional Chinese star names#Categories of Chinese traditional uranography, Chinese uranography, the modern constellation Cygnus (constellation), Cygnus is located within the northern quadrant of the sky, which is symbolized as the Black Tortoise (Chinese constellation), Black Tortoise of the North (北方玄武, ''Běi Fāng Xuán Wǔ''). The name of the western constellation in modern Chinese is 天鵝座 (''tiān é zuò''), meaning "the swan constellation".

Traditional Chinese Star Names
Chinese star names (Chinese language, Chinese: , ''xīng míng'') are named according to ancient Chinese astronomy and Chinese astrology, astrology. The sky is divided into Chinese constellations, star mansions (, ''xīng xiù'', also translated as "lodges") and asterisms (, ''xīng guān''). The ecliptic is divided into four sectors that are associated with the Four Symbols, guardians in Chinese mythology, and further into 28 mansions. Stars around the north celestial pole are grouped into three enclosures (, ''yuán''). The system of 283 asterisms under the Chinese constellations, 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 (Shang dynasty), Wuxian. Since the Han dynasty, Han and Jin dynasty (266–420), Jin dynasties, stars have been given reference numbers within their asterisms in a system similar to the Bayer ...

Deneb
Deneb () is a blue supergiant star in the constellation of Cygnus. It is the brightest star in the constellation and the 19th brightest in the night sky, with an apparent magnitude slightly varying between +1.21 and +1.29. Deneb is one of the vertices of the asterism known as the Summer Triangle and the "head" of the Northern Cross. Its Bayer designation is α Cygni, which is Latinised to Alpha Cygni, abbreviated to Alpha Cyg or α Cyg. Deneb rivals Rigel, a closer blue supergiant, as the most luminous first-magnitude star. However, its distance, and hence luminosity, is poorly known; its luminosity is estimated to be between 55,000 and 196,000 times that of the Sun. Distance estimates range from 1,400 to 2,600 light-years; assuming its highest value, it is the farthest star with an apparent magnitude brighter than 2.50. Nomenclature ''α Cygni'' (Latinised to ''Alpha Cygni'') is the star's designation given by Johann Bayer in 1603. The traditional name ''De ...

29 Cygni
29 Cygni is a single star in the northern constellation of Cygnus. It is dimly visible to the naked eye as a white-hued star with an apparent visual magnitude of 4.93. The distance to 29 Cyg, as estimated from an annual parallax shift of , is 133 light years. The star is moving closer to the Earth with a heliocentric radial velocity of −17 km/s. It is a member of the 30–50 million year old Argus Association of co-moving stars. This is an A-type main-sequence star with a stellar classification of A2 V. Rodríguez et al. (2000) classify it as a Delta Scuti variable with a frequency of 0.0267 cycles per day. It is a Lambda Boötis class chemically peculiar star and the first such star to be classified as a pulsating variable. 29 Cyg is multi-periodic, small-amplitude variable with a magnitude change of about 0.02 and a dominant period of 39 minutes. A magnetic field has been detected with an averaged quadratic field of . The star has a moderate ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
28 Cygni
28 Cygni is a binary star in the northern constellation of Cygnus. It is a faint blue-white hued star but visible to the naked eye with an apparent visual magnitude of 4.93. The distance to 28 Cyg, as estimated from its annual parallax shift of , is around 840 light years. It has an absolute magnitude of −2.56, which means that if the star were just away it would be brighter than Sirius, the brightest star in the night sky. This primary object is a B-type main-sequence star with a stellar classification of B2.5 V, per Lesh (1968). Slettebak (1982) found a class of B2 IV(e), which would suggest this is a more evolved subgiant star. It is a Be star, which means the spectrum displays emission lines due a disk of ejected gas in a Keplerian orbit around the star. The star displays short-term variability with two or more periods, and is classified as an SX Arietis variable by Samus et al. (2017). It is spinning rapidly with a projected rotational veloc ...

27 Cygni
27 Cygni is a subgiant star in the northern constellation of Cygnus. It is faintly visible to the naked eye with an apparent visual magnitude of 5.38. The distance to this system, as estimated from its annual parallax shift of , is 78.1 light-years. At that distance, the visual magnitude is diminished by an extinction of 0.05 due to interstellar dust. It is moving closer to the Earth with a heliocentric radial velocity of −33 km/s, and has a relatively high proper motion, traversing the celestial sphere at the rate of per year. 27 Cygni is a G-type subgiant with a stellar classification of G8.5 IVa, a star that has used up its core hydrogen and is starting to expand. It was found to be slightly variable by Percy et al. (1986), changing by up to 0.05 in visual magnitude with a characteristic time scale of 50–60 days. Further observations suggested a possible rotation period of around 42 days. Samus et al. (2017) classify it as a suspected R ...

Epsilon Cygni
Epsilon Cygni (ε Cygni, abbreviated Epsilon Cyg, ε Cyg) is a binary star in the constellation of Cygnus. With an apparent visual magnitude of 2.48, it is readily visible to the naked eye at night, and is the third-brightest star in the constellation. Based upon parallax measurement, Epsilon Cygni is about 73 light-years distant. The system has two confirmed constituents, Epsilon Cygni Aa (officially named Aljanah ) and Ab. Additionally, a visual companion (Epsilon Cygni C) is likely bound to the system. Nomenclature ''ε Cygni'' ( Latinised to ''Epsilon Cygni'') is the system's Bayer designation. The designations of the three constituents as ''Epsilon Cygni A'', ''B'' and ''C'', and those of ''A's'' components - ''Epsilon Cygni Aa'' and ''Ab'' - derive from the convention used by the Washington Multiplicity Catalog (WMC) for multiple star systems, and adopted by the International Astronomical Union (IAU). Epsilon Cygni bore the traditional name ''Gienah'' from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zeta Cygni
Zeta Cygni (ζ Cyg) is a binary star system in the northern constellation of Cygnus, the swan. It has an apparent visual magnitude of 3.26 and, based upon parallax measurements, is about away. The primary component, ζ Cyg A is a giant star with a spectral type of G8 IIIp. Its most likely status is as a red clump giant, an evolved star that has begun core helium fusion. It has around three times the mass of the Sun and has expanded to about 15 times the Sun's radius. It is radiating 112 times the brightness of the Sun from its outer atmosphere at an effective temperature of 4,910 K. At this temperature, the star glows with the yellow hue of a G-type star. The secondary component, ζ Cyg B, is a white dwarf of type DA4.2. The pair orbit each other every 6,489 days (17.8 years) with an eccentricity of 0.22. The white dwarf cannot be seen directly, but is estimated to have an apparent magnitude of 13.2. Zeta Cygni has an overabundance of barium, as well as oth ...
