Theta Tauri
Theta Tauri (θ Tauri, abbreviated Theta Tau, θ Tau) is a wide double star in the constellation of Taurus and a member of the Hyades open cluster. θ Tauri is composed of two 3rd magnitude stars, designated Theta Tauri (Theta Tauri B) and Theta Tauri (Theta Tauri A). Theta² is brighter, hence the pair are sometimes referred to as Theta Tauri B and A, respectively. They are separated by 5.62 arcminutes (0.094°) on the sky. Based upon parallax measurements, Theta¹ Tauri is located at a distance of , while Theta² Tauri is at a distance of . θ Tauri A and B are both spectroscopic binaries; the four components are designated Theta Tauri Aa (formally named Chamukuy ), Ab, Ba, and Bb. Nomenclature ''θ Tauri'' ( Latinised to ''Theta Tauri'') is the double star's Bayer designation; θ Tauri and θ Tauri those of its two constituents. The designations of the two constituents as ''Theta Tauri A'' and ''B'', and those of the four components - ''Theta Tauri Aa'', ''Ab'' ...

Latinisation Of Names
Latinisation (or Latinization) of names, also known as onomastic Latinisation, is the practice of rendering a ''non''-Latin name in a Latin style. It is commonly found with historical proper names, including personal names and toponyms, and in the standard binomial nomenclature of the life sciences. It goes further than romanisation, which is the transliteration of a word to the Latin alphabet from another script (e.g. Cyrillic). For authors writing in Latin, this change allows the name to function grammatically in a sentence through declension. In a scientific context, the main purpose of Latinisation may be to produce a name which is internationally consistent. Latinisation may be carried out by: * transforming the name into Latin sounds (e.g. for ), or * adding Latinate suffixes to the end of a name (e.g. for '' Meibom),'' or * translating a name with a specific meaning into Latin (e.g. for Italian ; both mean 'hunter'), or * choosing a new name based on some attribut ...

Delta3 Tauri
Delta3 Tauri (δ3 Tauri) is a binary star system in the zodiac constellation of Taurus. Based upon an annual parallax shift of 21.96 mas as seen from Earth, it is located roughly 149 light years distant from the Sun. It is visible to the naked eye with a combined apparent visual magnitude of +4.32. δ3 Tauri is separated from δ1 Tauri by 0.72° on the sky. This star also has the traditional Latin name Cleeia, from the Greek Kleeia (transliteration of Κλεεια), who was one of the Hyades sisters. It is considered a member of the Hyades cluster. In Chinese, (), meaning ''Net'', refers to an asterism consisting δ3 Tauri, ε Tauri, δ1 Tauri, γ Tauri, Aldebaran, 71 Tauri and λ Tauri. Consequently, the Chinese name for δ3 Tauri itself is (), "the Second Star of Net". [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epsilon Tauri
Epsilon Tauri or ε Tauri, formally named Ain (), is an orange giant star located approximately 45 parsecs (147 light-years) from the Sun in the constellation of Taurus. An extrasolar planet (designated Epsilon Tauri b, later named Amateru) is believed to be orbiting the star. It is a member of the Hyades open cluster. As such its age is well constrained at 625 million years. It is claimed to be the heaviest among planet-harboring stars with reliable initial masses although the star HD 13189 is potentially more massive. Given its large mass, this star, though presently of spectral type K0 III, was formerly of spectral type A that has now evolved off the main sequence into the giant phase. It is regarded as a red clump giant; that is, a core-helium burning star. Since Epsilon Tauri lies near the plane of the ecliptic, it is sometimes occulted by the Moon and (very rarely) by planets. It has an 11th magnitude companion 182 arcseconds from the primary. Nomenclature ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asterism (astronomy)
An asterism is an observed pattern or group of stars in the sky. Asterisms can be any identified pattern or group of stars, and therefore are a more general concept than the formally defined 88 constellations. Constellations are based on asterisms, but unlike asterisms, constellations outline and today completely divide the sky and all its celestial objects into regions around their central asterisms. For example, the asterism known as the Big Dipper comprises the seven brightest stars in the constellation Ursa Major. Another is the asterism of the Southern Cross, within the constellation of Crux. Asterisms range from simple shapes of just a few stars to more complex collections of many stars covering large portions of the sky. The stars themselves may be bright naked-eye objects or fainter, even telescopic, but they are generally all of a similar brightness to each other. The larger brighter asterisms are useful for people who are familiarizing themselves with the night sky. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chinese Astronomy
Astronomy in China has a long history stretching from the Shang dynasty, being refined over a period of more than 3,000 years. The ancient Chinese people have identified stars from 1300 BCE, as Chinese star names later categorized in the twenty-eight mansions have been found on oracle bones unearthed at Anyang, dating back to the mid-Shang dynasty. The core of the "mansion" (宿 ''xiù'') system also took shape around this period, by the time of King Wu Ding (1250–1192 BCE). Detailed records of astronomical observations began during the Warring States period (fourth century BCE) and flourished from the Han period onward. Chinese astronomy was equatorial, centered on close observation of circumpolar stars, and was based on different principles from those in traditional Western astronomy, where heliacal risings and settings of zodiac constellations formed the basic ecliptic framework. Joseph Needham has described the ancient Chinese as the most persistent and accurate obser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multiple Star
A star system or stellar system is a small number of stars that orbit each other, bound by gravitational attraction. A large group of stars bound by gravitation is generally called a ''star cluster'' or ''galaxy'', although, broadly speaking, they are also star systems. Star systems are not to be confused with planetary systems, which include planets and similar bodies (such as comets). A star system of two stars is known as a ''binary star'', ''binary star system'' or ''physical double star''. If there are no tidal effects, no perturbation from other forces, and no transfer of mass from one star to the other, such a system is stable, and both stars will trace out an elliptical orbit around the barycenter of the system indefinitely. ''(See Two-body problem)''. Examples of binary systems are Sirius, Procyon and Cygnus X-1, the last of which probably consists of a star and a black hole. Multiple star systems A multiple star system consists of three or more stars that appear f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IAU Working Group On Star Names
The International Astronomical Union (IAU) established a Working Group on Star Names (WGSN) in May 2016 to catalog and standardize proper names for stars for the international astronomical community. It operates under Division C – Education, Outreach and Heritage. The IAU states that it is keen to make a distinction between the terms ''name'' and ''designation''. To the IAU, ''name'' refers to the (usually colloquial) term used for a star in everyday conversation, while ''designation'' is solely alphanumerical, and used almost exclusively in official catalogues and for professional astronomy. (The WGSN notes that transliterated Bayer designations (e.g., Tau Ceti) are considered a special historical case and are treated as designations.) Terms of reference The terms of reference for the WGSN for the period 2016–2018 were approved by the IAU Executive Committee at its meeting on 6 May 2016. In summary, these are to: * establish IAU guidelines for the proposal and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yucatec Maya Language
Yucatec Maya (; referred to by its speakers simply as Maya or as , is one of the 32 Mayan languages of the Mayan language family. Yucatec Maya is spoken in the Yucatán Peninsula and northern Belize. There is also a significant diasporic community of Yucatec Maya speakers in San Francisco, though most Mayan Americans are speakers of other Mayan languages from Guatemala and Chiapas. Etymology According to the Hocabá dictionary, compiled by American anthropologist Victoria Bricker, there is a variant name , literally "flat speech"). A popular, yet false, alternative etymology of Mayab is "ma ya'ab" or "not many," "the few" which derives from New Age spiritualist interpretations of the Maya. The use of "Mayab" as the name of the language seems to be unique to the town of Hocabá, as indicated by the Hocabá dictionary and is not employed elsewhere in the region or in Mexico, by either Spanish or Maya speakers. As used in Hocabá, "Mayab" is not the recognized name of the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maya Peoples
The Maya peoples () are an ethnolinguistic group of Indigenous peoples of the Americas, indigenous peoples of Mesoamerica. The ancient Maya civilization was formed by members of this group, and today's Maya are generally descended from people who lived within that historical region. Today they inhabit southern Mexico, Guatemala, Belize, El Salvador, and Honduras. "Maya" is a modern collective term for the peoples of the region, however, the term was not historically used by the indigenous populations themselves. There was no common sense of identity or political unity among the distinct populations, societies and ethnic groups because they each had their own particular traditions, cultures and historical identity. It is estimated that seven million Maya were living in this area at the start of the 21st century. Guatemala, southern Mexico and the Yucatán Peninsula, Belize, El Salvador, and western Honduras have managed to maintain numerous remnants of their ancient cultural her ...

Mythology
Myth is a folklore genre consisting of narratives that play a fundamental role in a society, such as foundational tales or origin myths. Since "myth" is widely used to imply that a story is not objectively true, the identification of a narrative as a myth can be highly controversial. Many adherents of religions view their own religions' stories as truth and so object to their characterization as myth, the way they see the stories of other religions. As such, some scholars label all religious narratives "myths" for practical reasons, such as to avoid depreciating any one tradition because cultures interpret each other differently relative to one another. Other scholars avoid using the term "myth" altogether and instead use different terms like "sacred history", "holy story", or simply "history" to avoid placing pejorative overtones on any sacred narrative. Myths are often endorsed by secular and religious authorities and are closely linked to religion or spirituality. Many soc ...
