14 Andromedae
14 Andromedae, abbreviated 14 And, also named Veritate , is a single, orange-hued giant star situated approximately 247 light-years away in the northern constellation of Andromeda. It is dimly visible to the naked eye with an apparent visual magnitude of 5.22. The star is moving closer to the Earth with a heliocentric radial velocity of −60 km/s. In 2008 an extrasolar planet (designated 14 Andromedae b, later named ''Spe'') was discovered to be orbiting the star. This is a red clump giant with a stellar classification of K0 III, indicating it is on the horizontal branch and is generating energy through helium fusion at its core. The star has 1.12 (or 2.2) times the mass of the Sun and has expanded to 10.5 times the Sun's radius. It is radiating 60.3 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,743 K. It is thought it was formerly an A- or F-type main-sequence star earlier in its life, prior to evolvi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andromeda (constellation)
Andromeda is one of the 48 constellations listed by the 2nd-century Greco-Roman astronomer Ptolemy, and one of the 88 modern constellations. Located in the northern celestial hemisphere, it is named for Andromeda, daughter of Cassiopeia, in the Greek myth, who was chained to a rock to be eaten by the sea monster Cetus. Andromeda is most prominent during autumn evenings in the Northern Hemisphere, along with several other constellations named for characters in the Perseus myth. Because of its northern declination, Andromeda is visible only north of 40° south latitude; for observers farther south, it lies below the horizon. It is one of the largest constellations, with an area of 722 square degrees. This is over 1,400 times the size of the full moon, 55% of the size of the largest constellation, Hydra, and over 10 times the size of the smallest constellation, Crux. Its brightest star, Alpha Andromedae, is a binary star that has also been counted as a part of Pegasus, while ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 electromagnetic radiation. Effective temperature is often used as an estimate of a body's surface temperature when the body's emissivity curve (as a function of wavelength) is not known. When the star's or planet's net emissivity in the relevant wavelength band is less than unity (less than that of a black body), the actual temperature of the body will be higher than the effective temperature. The net emissivity may be low due to surface or atmospheric properties, including greenhouse effect. Star The effective temperature of a star is the temperature of a black body with the same luminosity per ''surface area'' () as the star and is defined according to the Stefan–Boltzmann law . Notice that the total (bolometric) luminosity of a star is then , where is the stellar radius. The definition of the stellar radius is obviously not straightf ...

490 Veritas
Veritas, minor planet designation 490 Veritas, is a carbonaceous Veritasian asteroid, which may have been involved in one of the more massive asteroid-asteroid collisions of the past 100 million years. It was discovered by German astronomer Max Wolf at Heidelberg Observatory on 3 September 1902. Description With an diameter of more than 100 kilometers, Veritas is the largest member and namesake of the Veritas family, a mid-sized asteroid family of carbonaceous asteroids in the outer main-belt, that formed recently approximately million years ago. David Nesvorný of the Southwest Research Institute in Boulder traced the orbits of these bodies back in time, and calculated that they formed in a collision of a body at least 150 km in diameter with a smaller asteroid. Veritas and Undina would have been the largest fragments of that collision which caused a "late Miocene dust shower". The family consists of more than a thousand known members including 1086 Nata, 2428 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ablative (Latin)
In Latin grammar, the ablative case () is one of the six cases of nouns. Traditionally, it is the sixth case (). It has forms and functions derived from the Proto-Indo-European ablative, instrumental, and locative. It expresses concepts similar to those of the English prepositions ''from''; ''with'', ''by''; and ''in'', ''at''. It is sometimes called the adverbial case, since phrases in the ablative can be translated as adverbs: , "with incredible speed", or "very quickly". Uses Ablative proper Some uses of the ablative descend from the Proto-Indo-European ablative case. * Ablative of separation implies that some person or thing is separated from another. No active movement from one location to the next occurs; furthermore, ablatives of separation sometimes lack a preposition, particularly with certain verbs like ''careō'' or ''līberō''. For example, ''Cicerō hostēs ab urbe prohibuit'', "Cicero kept the enemy away from the city"; ''eōs timōre līberāvit'', "he freed the ...

Spes
In ancient Roman religion, Spes (pronounced ) was the goddess of hope. Multiple temples to Spes are known, and inscriptions indicate that she received private devotion as well as state cult. Republican Hope During the Republic, a temple to "ancient Hope" ''(Spes vetus)'' was supposed to have been located near the Praenestine Gate. It was associated with events that occurred in the 5th century BC, but its existence as anything except perhaps a private shrine has been doubted. A well-documented temple of Spes was built by Aulus Atilius Calatinus along with Fides, as the result of vows ''(vota)'' made to these goddesses during the First Punic War. At Capua in 110 BC, a temple was built to the triad of Spes, Fides, and Fortuna. Imperial Hope Spes was one of the divine personifications in the Imperial cult of the Virtues. Spes Augusta was Hope associated with the capacity of the emperor as ''Augustus'' to ensure blessed conditions. Like Salus ("Salvation, Security"), Ops ("Abunda ...

Veritas
Veritas is the name given to the Roman virtue of Honesty, truthfulness, which was considered one of the main virtues any good Roman should possess. The Greek goddess of truth is Aletheia (Ancient Greek language, Ancient Greek: ). The German philosopher Martin Heidegger argues that the truth represented by ''aletheia'' (which essentially means "unconcealment") is different from that represented by ''veritas'', which is linked to a Roman understanding of rightness and finally to a Nietzschean sense of justice and a will to power. In Roman mythology, Veritas (), meaning Truth, is the Goddess of Truth, a daughter of Saturn (mythology), Saturn (called Cronus by the Greeks, the Titan (mythology), Titan of Time, perhaps first by Plutarch), and the mother of Virtus (deity), Virtus. She is also sometimes considered the daughter of Jupiter (mythology), Jupiter (called Zeus by the Greeks), or a creation of Prometheus. The elusive goddess is said to have hidden in the bottom of a holy well. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin (language)
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

NameExoWorlds
NameExoWorlds (also known as IAU NameExoWorlds) is the name of various projects managed by the International Astronomical Union (I.A.U.) to encourage names to be submitted for astronomical objects, which would later be considered for official adoption by the organization. History The first such project (NameExoWorlds I), in 2015, regarded the naming of stars and exoplanets. 573,242 votes were submitted by members by the time the contest closed on October 31, 2015, and the names of 31 exoplanets and 14 stars were selected from these. Many of the names chosen were based on world history, mythology and literature. In June 2019, another such project (NameExoWorlds II), in celebration of the organization's hundredth anniversary, in a project officially called IAU100 NameExoWorlds, welcomed countries of the world to submit names for exoplanets and their host stars. A star with an exoplanet was assigned to each country, and members of the public submitted names for them. In August 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Astronomical Union
The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded in 1919 and is based in Paris, France. The IAU is composed of individual members, who include both professional astronomers and junior scientists, and national members, such as professional associations, national societies, or academic institutions.

Flamsteed Designation
A Flamsteed designation is a combination of a number and constellation name that uniquely identifies most naked eye stars in the modern constellations visible from southern England. They are named for John Flamsteed who first used them while compiling his '' Historia Coelestis Britannica''. (Flamsteed used a telescope, and the catalog also includes some stars which are relatively bright but not necessarily visible with the naked eye.) Description Flamsteed designations for stars are similar to Bayer designations, except that they use numbers instead of Greek and Roman letters. Each star is assigned a number and the Latin genitive of the constellation it lies in (see 88 modern constellations for a list of constellations and the genitive forms of their names). Flamsteed designations were assigned to 2554 stars. The numbers were originally assigned in order of increasing right ascension within each constellation, but due to the effects of precession they are now slightly out of o ...
