Telescopium (Chinese Astronomy)
The modern constellation Telescopium lies across one of the quadrants symbolized by the Black Tortoise (Chinese constellation), Black Tortoise of the North (北方玄武, ''Běi Fāng Xuán Wǔ''), and Chinese constellations#The Southern Asterisms (近南極星區), The Southern Asterisms (近南極星區, ''Jìnnánjíxīngōu''), that divide the sky in traditional Traditional Chinese star names#Categories of Chinese traditional uranography, Chinese uranography. The name of the western constellation in modern Chinese is 望遠鏡座 (''wàng yuǎn jìng zuò''), meaning "the telescope constellation".

Telescopium
Telescopium is a minor constellation in the southern celestial hemisphere, one of twelve named in the 18th century by French astronomer Nicolas-Louis de Lacaille and one of several depicting scientific instruments. Its name is a Latinized form of the Greek word for telescope. Telescopium was later much reduced in size by Francis Baily and Benjamin Gould. The brightest star in the constellation is Alpha Telescopii, a blue-white subgiant with an apparent magnitude of 3.5, followed by the orange giant star Zeta Telescopii at magnitude 4.1. Eta and PZ Telescopii are two young star systems with debris disks and brown dwarf companions. Telescopium hosts two unusual stars with very little hydrogen that are likely to be the result of two merged white dwarfs: PV Telescopii, also known as HD 168476, is a hot blue extreme helium star, while RS Telescopii is an R Coronae Borealis variable. RR Telescopii is a cataclysmic variable that brightened as a nova to magnitude 6 in 1948. Tele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Tortoise (Chinese Constellation)
The Black Tortoise () is one of the Four Symbols of the Chinese constellations. Despite its English name, it is usually depicted as a tortoise entwined together with a snake. The name used in East Asian languages does not mention either animal; the alternative name "Black Warrior ~ Dark Warrior ~ Mysterious Warrior" is a more faithful translation. It represents the north and the winter season, thus it is sometimes called Xuanwu (Black Tortoise, lit. Black Warrior) of the North (). In Japan, it is named Genbu. It is said to protect Kyoto on the north side, being one of the four guardian spirits that protect the city. It is represented by the Kenkun Shrine, which is located on top of Mt Funaoka in Kyoto. The creature's name is identical to that of the important Taoist god Xuanwu, who is sometimes (as in ''Journey to the West'') portrayed in the company of a turtle and a snake. History During the Han dynasty, people often wore jade pendants that were in the shape of turtle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

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.

Dipper (Chinese Constellation)
The Dipper mansion (斗宿, pinyin: Dǒu Xiù) is one of the Twenty-eight mansions of the Chinese constellations. It is one of the northern mansions of the Black Tortoise. In Taoism, it is known as the "Six Stars of the Southern Dipper" (南斗六星, Nándǒu liù xīng), in contrast to the Big Dipper The Big Dipper ( US, Canada) or the Plough ( UK, Ireland) is a large asterism consisting of seven bright stars of the constellation Ursa Major; six of them are of second magnitude and one, Megrez (δ), of third magnitude.

Alpha Telescopii
Alpha Telescopii, Latinized from α Telescopii, is the brightest star in the southern constellation of Telescopium, with an apparent visual magnitude of 3.5. The ancient Roman astronomer Ptolemy included it in the constellation Corona Australis, but it was moved to Telescopium when that constellation was created by French astronomer Nicolas Louis de Lacaille in the 18th century. Parallax measurements put it at a distance of from Earth. At that range, the visual magnitude of the star is diminished by an extinction of 0.22 due to interstellar dust. Properties Physical Characteristics This star is much larger than the Sun, with an estimated times the mass and times the radius. The spectrum of the star matches a stellar classification of B3 IV, where the luminosity class of 'IV' indicates this is a subgiant star that has nearly exhausted the supply of hydrogen at its core and is evolving away from the main sequence. Alpha Telescopii is a bright star that is radia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HD 187420
HD 187420 (HR 7548; 71 G. Telescopii) and HD 187421 (HR 7549; 72 G. Telescopii), are the components of a binary star located in the southern constellation Telescopium. Gaia DR3 parallax measurements place the stars at a distance of 407 and 414 light years respectively. The two are separated by , and they are approaching the Solar System with heliocentric radial velocities of and −21.5 km/s respectively. The system HD 187420 is the primary of the system. It has an apparent magnitude of 5.71, making it faintly visible to the naked eye as a yellowish-orange-hued star. However, its brightness is diminished by 0.17 magnitudes due to interstellar dust. Meanwhile, the secondary HD 187421 has an apparent magnitude of 6.37, placing it near the limit for naked eye visibility. It too suffers from extinction, which makes it 0.25 magnitudes dimmer. The stars have absolute magnitudes of −0.33 and +2.69 respectively. HD 187421 is located 23.5" away from HD 187420 along a pos ...
