Bharani (star)
41 Arietis (abbreviated 41 Ari) is a triple star system in the northern constellation of Aries. With an apparent visual magnitude of 3.63, this system is readily visible to the naked eye. It has an annual parallax shift of 19.69 mas, which indicates it is at a distance of from the Sun. The system consists of a binary pair, designated 41 Arietis A, together with a third companion star, 41 Arietis D. (41 Arietis B and C form optical pairs with A, but are not physically related.) The components of A are themselves designated 41 Arietis Aa (formally named Bharani ) and Ab. Nomenclature ''41 Arietis'' is the system's Flamsteed designation. It does not possess a Greek-letter Bayer designation, since this system was once part of the now-obsolete constellation Musca Borealis, but is sometimes designated ''c Arietis''. The designations of the two constituents as ''41 Arietis A'' and ''D'', and those of ''A's'' components - ''41 Arietis Aa'' and ''Ab'' - derive from ...

Aries (constellation)
Aries is one of the constellations of the zodiac. It is located in the Northern celestial hemisphere between Pisces to the west and Taurus to the east. The name Aries is Latin for ram. Its old astronomical symbol is (♈︎). It is one of the 48 constellations described by the 2nd century astronomer Ptolemy, and remains one of the 88 modern constellations. It is a mid-sized constellation ranking 39th in overall size, with an area of 441 square degrees (1.1% of the celestial sphere). Aries has represented a ram since late Babylonian times. Before that, the stars of Aries formed a farmhand. Different cultures have incorporated the stars of Aries into different constellations including twin inspectors in China and a porpoise in the Marshall Islands. Aries is a relatively dim constellation, possessing only four bright stars: Hamal (Alpha Arietis, second magnitude), Sheratan (Beta Arietis, third magnitude), Mesarthim (Gamma Arietis, fourth magnitude), and 41 Arietis (also fourt ...

Bayer Designation
A Bayer designation is a stellar designation in which a specific star is identified by a Greek or Latin letter followed by the genitive form of its parent constellation's Latin name. The original list of Bayer designations contained 1,564 stars. The brighter stars were assigned their first systematic names by the German astronomer Johann Bayer in 1603, in his star atlas ''Uranometria''. Bayer catalogued only a few stars too far south to be seen from Germany, but later astronomers (including Nicolas-Louis de Lacaille and Benjamin Apthorp Gould) supplemented Bayer's catalog with entries for southern constellations. Scheme Bayer assigned a lowercase Greek letter (alpha (α), beta (β), gamma (γ), etc.) or a Latin letter (A, b, c, etc.) to each star he catalogued, combined with the Latin name of the star's parent constellation in genitive (possessive) form. The constellation name is frequently abbreviated to a standard three-letter form. For example, Aldebaran in the constellation ...

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] |
35 Arietis
35 Arietis (abbreviated 35 Ari) is a binary star in the northern constellation of Aries. ''35 Arietis'' is the Flamsteed designation. It is approximately distant from the Earth, based upon an annual parallax shift of 9.51 mas. This star is visible to the naked eye with an apparent visual magnitude of 4.64. This is a single-lined spectroscopic binary system, with the presence of a companion being demonstrated by shifts in the spectrum of the primary component. The pair orbit each other with a period of 490.0 days and an eccentricity of 0.14. The primary is a B-type main-sequence star with a stellar classification of B3 V. With a mass around 5.7 times that of the Sun, it is radiating 870 times the Sun's luminosity. This energy is being emitted from the outer atmosphere at an effective temperature of 17,520 K, causing it to shine with the blue-white hue of a B-type star A B-type main-sequence star (B V) is a main-sequence (hydrogen-burning) st ...

Lunar Mansion
Often called lunar mansion, a lunar station or lunar house is a segment of the ecliptic through which the Moon passes in its orbit around the Earth. The concept was used by several ancient cultures as part of their calendrical system. Stations in different cultures In general, though not always, the zodiac is divided into 27 or 28 segments relative to the vernal equinox point or the fixed stars – one for each day of the lunar month. (A sidereal month lasts about days.) The Moon's position is charted with respect to those fixed segments. Since the Moon's position at any given stage will vary according to Earth's position in its own orbit, lunar stations are an effective system for keeping track of the passage of seasons. Various cultures have used sets of lunar stations astrologically; for example, the Jyotisha astrological ''nakshatras'' of Hindu culture, the Arabic manzils (''manazil al-qamar''), the Twenty-Eight Mansions of Chinese astronomy, and the 36 ''d ...

Nakshatra
Nakshatra ( sa, नक्षत्रम्, translit=Nakṣatram) is the term for lunar mansion in Hindu astrology and Indian Astronomy. A nakshatra is one of 27 (sometimes also 28) sectors along the ecliptic. Their names are related to a prominent star or asterisms in or near the respective sectors. The starting point for the nakshatras according to Vedas is "Krittika" (it has been argued because the Pleiades may have started the year at the time the Vedas were compiled, presumably at the vernal equinox), but, in more recent compilations, the start of the nakshatras list is the point on the ecliptic directly opposite to the star Spica called ''Chitrā'' in Sanskrit, which would be Ashwinī, a part of the modern constellation Aries, and these compilations therefore may have been compiled during the centuries when the sun was passing through the area of the constellation Aries at the time of the vernal equinox. This version may have been called ''Meshādi'' or the " start ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bharani
Bharani (Devanagari: भरणी) is the second nakshatra in Hindu astronomy, corresponding to 35, 39, and 41 Arietis all together. In Jyotiṣa, Bharani is ruled by Shukra (the planet Venus). Also, it is classified as a Cruel or Active nakshatra, meaning that, under electional astrological beliefs, works of a harmful or deceptive nature are best conducted while the moon is Bharani. Bharani is seen as being under the domain of Yama, the god of death or Kālī. Dennis M. Harness. ‘’ The Nakshatras: The Lunar Mansions of Vedic Astrology’.’ Lotus Press, 1999. . pg. 7 Traditional Hindu given names are determined by which pada (quarter) of a nakshatra the Ascendant/Lagna was in at the time of birth. The given name would begin with the following syllables: *A (pronounced as in "agglutination") * Ee (pronounced as in "Eel") * Li (pronounced as in "little") *Lu (pronounced as in "look") *Le (pronounced as in "levity") *Lo (pronounced as in "local") See also *List of Naksh ...

Indian Astronomy
Astronomy has long history in Indian subcontinent stretching from pre-historic to modern times. Some of the earliest roots of Indian astronomy can be dated to the period of Indus Valley civilisation or earlier. Astronomy later developed as a discipline of Vedanga, or one of the "auxiliary disciplines" associated with the study of the Vedas,Sarma (2008), ''Astronomy in India'' dating 1500 BCE or older. The oldest known text is the ''Vedanga Jyotisha'', dated to 1400–1200 BCE (with the extant form possibly from 700 to 600 BCE). Indian astronomy was influenced by Greek astronomy beginning in the 4th century BCEHighlights of Astronomy, Volume 11B: As presented at the XXIIIrd General Assembly of the IAU, 1997.

39 Arietis
39 Arietis (abbreviated 39 Ari), officially named Lilii Borea , is a star in the northern constellation of Aries. It is visible to the naked eye with an apparent visual magnitude of +4.5. The distance to this star, as determined from an annual parallax shift of 19.01 mas, is approximately . Nomenclature ''39 Arietis'' is the star's Flamsteed designation. This star was described as ''Lilii Borea'' by Nicolas-Louis de Lacaille in 1757, as a star of the now-defunct constellation of Lilium (the Lily). The words are simply the Latin phrase ''Līliī Boreā'' 'in the north of Lilium'. ''Līliī Austrīnā'' 'in the south of Lilium' was 41 Arietis. In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. The WGSN approved the name ''Lilii Borea'' for this star on 5 September 2017 and it is now so included in the List of IAU-approved Star Names. In Chinese, (), meaning ''Stomach ...

Fleur-de-lis
The fleur-de-lis, also spelled fleur-de-lys (plural ''fleurs-de-lis'' or ''fleurs-de-lys''), is a lily (in French, and mean 'flower' and 'lily' respectively) that is used as a decorative design or symbol. The fleur-de-lis has been used in the heraldry of numerous European nations, but is particularly associated with France, notably during its monarchical period. The fleur-de-lis became "at one and the same time, religious, political, dynastic, artistic, emblematic, and symbolic," especially in French heraldry. The fleur-de-lis has been used by French royalty and throughout history to represent saints of France. In particular, the Virgin Mary and Saint Joseph are often depicted with a lily. The fleur-de-lis is represented in Unicode at in the Miscellaneous Symbols block. Origin The ''fleur de lis'' is widely thought to be a stylized version of the species ''Iris pseudacorus'', or ''Iris florentina''.Stefan Buczacki However, the lily (genus lilium, family Liliaceae) and the ...

Lilium (constellation)
''Lilium'' () is a genus of herbaceous flowering plants growing from bulbs, all with large prominent flowers. They are the true lilies. Lilies are a group of flowering plants which are important in culture and literature in much of the world. Most species are native to the northern hemisphere and their range is temperate climates and extends into the subtropics. Many other plants have "lily" in their common names, but do not belong to the same genus and are therefore not true lilies. Description Lilies are tall perennials ranging in height from . They form naked or tunicless scaly underground bulbs which are their organs of perennation. In some North American species the base of the bulb develops into rhizomes, on which numerous small bulbs are found. Some species develop stolons. Most bulbs are buried deep in the ground, but a few species form bulbs near the soil surface. Many species form stem-roots. With these, the bulb grows naturally at some depth in the soil, and each yea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicolas-Louis De Lacaille
Abbé Nicolas-Louis de Lacaille (; 15 March 171321 March 1762), formerly sometimes spelled de la Caille, was a kingdom of France, French astronomer and geodesist who named 14 out of the IAU designated constellations, 88 constellations. From 1750 to 1754, he studied the sky at the Cape Colony, Cape of Good Hope in present-day South Africa. Lacaille observed over 10,000 stars using just a small telescope, half-inch refracting telescope. Biography Born at Rumigny, Ardennes, Rumigny in the Ardennes in eastern France, he attended school in Mantes-sur-Seine (now Mantes-la-Jolie). Afterwards, he studied rhetoric and philosophy at the :fr:Collège de Lisieux, Collège de Lisieux and then theology at the Collège de Navarre. He was left destitute in 1731 by the death of his father, who had held a post in the household of the duchess of Vendôme. However, he was supported in his studies by the Louis Henri, Duke of Bourbon, Duc de Bourbon, his father's former patron. After he graduated, h ...
