[note 3] (Compare this, for example, to a threefold metallicity abundance in the similar star Sirius as compared to the Sun.) You're looking for a bright blue-white star. Although Vega is at present only the fifth-brightest star in the night sky, the star is slowly brightening as proper motion causes it to approach the Sun. Observations by the CHARA array in 2005–06 confirmed this deduction.[12]. While the Sun has a central radiation zone at its core covered by a convection zone, Vega has a convection zone at its core that distributes ash from its nuclear reaction. [53] In 1983, Vega became the first star found to have a disk of dust. One possibility is that the chemical peculiarity may be the result of diffusion or mass loss, although stellar models show that this would normally only occur near the end of a star's hydrogen-burning lifespan. From Earth, Vega is observed from the direction of one of these poles. [68], Vega has a rotation period of 12.5 hours. Cornelius Agrippa listed its kabbalistic sign under Vultur cadens, a literal Latin translation of the Arabic name. These much wider disks were found to be circular and free of clumps, with dust particles ranging from 1–50 μm in size. https://www.thoughtco.com/vega-star-facts-4137641 (accessed January 27, 2021). If the Sun was viewed from Vega, in contrast, its magnitude would only be a faint 4.3. [23], By 2005, the Spitzer Space Telescope had produced high-resolution infrared images of the dust around Vega. To the ancient Greeks, the constellation Lyra was formed from the harp of Orpheus, with Vega as its handle. Celestia Vega is not only a YouTuber, she's currently working as a porn star. What are synonyms for vega? It was shown to extend out to 43″ (330 AU) at a wavelength of 24 μm, 70″ (543 AU) at 70 μm and 105″ (815 AU) at 160 μm. Tied up with Jupiter or Venus, Vega is said to pave the way to riches and fame. [60][61] The lines of other elements are relatively weak, with the strongest being ionized magnesium, iron, and chromium. A complete precession cycle requires 25,770 years,[30] during which time the pole of the Earth's rotation follows a circular path across the celestial sphere that passes near several prominent stars. (2012)[98] and the Herschel Space Telescope. What does VEGA mean? [85], Subsequent measurements of Vega at 193 μm showed a lower than expected flux for the hypothesized particles, suggesting that they must instead be on the order of 100 μm or less. In a good cosmic configuration, Vega is supposed to give artistic talents especially for music and acting, but also a liking for good living. The traditional name Vega (earlier Wega[14]) comes from a loose transliteration of the Arabic word wāqi‘ meaning "falling" or "landing", via the phrase an-nasr al-wāqi‘, "the falling eagle". In astronomy, those elements with higher atomic numbers than helium are termed "metals". [76], The observed helium to hydrogen ratio in Vega is 0.030±0.005, which is about 40% lower than the Sun. It is the fifth-brightest star in the night sky, and the second-brightest star in the northern celestial hemisphere, after Arcturus. In the Galactic coordinate system, the space velocity components of Vega are (U, V, W) = (−16.1 ± 0.3, −6.3 ± 0.8, −7.7 ± 0.3) km/s, for a net space velocity of 19 km/s. How do you use vega in a sentence? The magnitude of Vega was measured again in 1981 at the David Dunlap Observatory and showed some slight variability. 230, Verses 8–11). As a result, content that stays on the FANDOM domain … [Medieval Latin, from Arabic (an-nasr) al-wāqi', the falling (eagle), Vega : al-, the + wāqi', falling, active participle of waqa'a, to fall; see wqʕ in Semitic roots.] This is the first such detection of a magnetic field on a spectral class A star that is not an Ap chemically peculiar star. Thus the velocity can be measured from the amount of shift of the star's spectrum. Many allow you to wave the phone across the sky until you see the name. [31] Vega is the brightest of the successive northern pole stars. Hopkins in 2011,[88] revealed evidence for an inner dust band around Vega. The name Vega means Stooping Eagle and is of Arabic origin.Vega is a name that's been used primarily by parents who are considering baby names for girls.. Name of the brightest star in the Lyra constellation. It is believed that these may provide clues to the origin of the Solar System. It is definitely of the nature of Venus. Vega is seen in the summer sky in the Northern Hemisphere, where it is part of the constellation Lyra. [92], Determining the nature of the planet has not been straightforward; a 2002 paper hypothesizes that the clumps are caused by a roughly Jupiter-mass planet on an eccentric orbit. For comparison, the Sun has an abundance of elements heavier than helium of about ZSol = 0.0172±0.002. As viewed from the poles, this results in a darker (lower-intensity) limb than would normally be expected for a spherically symmetric star. Thus the dust is more likely created by a debris disk around Vega, rather than from a protoplanetary disk as was earlier thought. The unusually low metallicity of Vega makes it a weak Lambda Boötis star. Vega is the fifth-brightest star in the night sky and the second-brightest star in the northern celestial hemisphere (after Arcturus). Dust would collect in orbits that have mean-motion resonances with this planet—where their orbital periods form integer fractions with the period of the planet—producing the resulting clumpiness. [note 4][79], One of the early results from the Infrared Astronomy Satellite (IRAS) was the discovery of excess infrared flux coming from Vega, beyond what would be expected from the star alone. [58], The energy flux from Vega has been precisely measured against standard light sources. [118] Medieval star charts also listed the alternate names Waghi, Vagieh and Veka for this star.[29]. This process becomes dominant at a temperature of about 17 million K,[56] which is slightly higher than the core temperature of the Sun, but is less efficient than the Sun's proton-proton chain reaction fusion reaction.
