Vega is also known as Alpha Lyrae (α Lyrae, Alpha Lyr, α Lyr), as it is the principle star in the constellation Lyra, the lyre. Near Vega is Epsilon Lyrae, the famed “double-double” star. Other stars that display excessive dust when viewed in the infrared spectrum are called Vega-like or Vega-excess stars. “Main sequence” again testifies to the fact that it belongs in the category of normal stars, and that it produces energy through stable fusion of hydrogen into helium. It’s sometimes called the Harp Star. Finder chart. Right now, Vega is about 455 million years old or half-way through its main-sequence life. "Absolute magnitude" is defined as the magnitude a star would have if we picked it up and placed it exactly 10 parsecs away from the Sun; that's very roughly as close as the star Vega, and a bit more distant than the Sun's closest neighbors. Vega: Buy Vega hair brushes, combs, pedicure, manicure, bath and beauty accessories Online from Vega. The dust is found mainly in a disk around the star rather than a sphere, with particle sizes estimated to be between 1 to 50 microns in diameter. The name of the color scheme to use or an array of color values. Although Vega and the Sun are both stars, they are very different from one another. It is not visible south of 51° S, so it cannot be seen at all from the southern part of South America or Antarctica. Size of the star Vega in contrast to our sun. Then … you know the story. As a black body gets hotter its col… The other two stars in the Triangle are Deneb and Altair. 5. Vega’s spectral type is A (white) and its luminosity class V (main sequence). The convection zone is in equilibrium with the star's atmosphere. The equator of Vega is 19% bigger than its polar radius. Mass is approximately 2.3 to 3.1 times the mass of the sun. And the kids in her Radiant Hillsneighborhood were just as lucky. Thanks to its high brightness, Vega is clearly visible when observed from locations with dark skyes, and should be also quite easily visible from light polluted areas. Vega is at the top of the triangle, with Deneb below it and to the left and Altair below both stars and to the right. The blue-white star Vega via Fred Espenak. Star-crossed lovers Zhinu – represented by the star Vega in the constellation Lyra – and a humble farm boy, Niulang, represented by the star Altair in Aquila. Vega appears to be surrounded by a disk of dust. Product Overview: Spec Sheet VG10 & VG16 Series Specification Sheet VG10 & VG16 Series Specification Sheet_Spanish […] The colour of a star is primarily a function of its effective temperature. 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. They can have blue skin and are said to look like Vulcans (from Star Trek), or they may look like dark-skinned Orientals or East Indians. There are also non-humanoids from Vega that are insectoid or reptilian, with greenish tinted skin, ranging from flesh color to black, with large eyes.They represent the first masculine polarization within Lyra. While Vega fuses hydrogen, most of the energy at its core comes from the carbon-nitrogen-oxygen (CNO cycle) in which protons combine to form helium with intermediate nuclei of the elements carbon, nitrogen, and oxygen, This process is less efficient than the Sun's proton-proton chain reaction fusion and requires a high temperature of about 15 million Kelvin. Source. The table below summarizes the key facts about Vega: Color of Vega ⬤ Image via Anhellica/ Lilliacerise’s blog. If it were spinning about 10% faster, it would break apart! In general, a star's temperature determines its color, from red to blue-white. This is because Vegas has over twice the mass of the Sun and is spinning so rapidly (236.2 km/s at its equator), that it experiences centrifugal effects. The history of the star: Vega. From a latitude including New York and Madrid, Vega is only below the horizon about seven hours a day, so it can be viewed any night of the year. The Earth's axis of rotation precesses, like a wobbling toy top, which means "north" changes over a period of around 26,000 years. In 2016 I’ve visited Vietnam. In that case, Orihime’s tears form raindrops that fall over Japan. Further south, Vega is below the horizon more of the time and may be trickier to find. Come to know it, and you will see. But when Orihime’s father finds out, he is enraged and forbids her to see this mere mortal. In Japan, Vega is called Orihime, a celestial princess or goddess. Why do stars have different colours? It’s about 25 light-years away. from p.284 of Star Names, Richard Hinckley Allen, 1889. With a visual magnitude (apparent brightness) of 0.03, Vega is only marginally dimmer than Arcturus, but with a distinctly different, cool-blue color. Apply nail color of your choice. Vega in history and myth. Vega is one of the brightest stars in the night sky. Its current age is about 455 million years. Astronomers believe the dust may have resulted from collisions between objects in a debris disk. 4. age main sequence star like Vega star estimated to be about 1 billion years old, compared with the Sun which is expected to reach the age of 10 billion years. She has taught science courses at the high school, college, and graduate levels. Vega is a bluish-white star with a radius of around 1.1 million miles (1.8 million km), which is around two and a half times the size of the sun. You can see the Summer Triangle in the evening beginning around June, through the end of each year. The G is the general spectral type, G is a main-sequence star, or of yellow color and the 2 means that it is 2/10 of the way to a spectral type K and V is its luminosity and classifies the Sun as either a dwarf or more properly a main-sequence star. In western skylore, Vega’s constellation Lyra is said to be the harp played by the legendary Greek musician Orpheus. Libby is positively got Inflate radiant inside and out. Vega's spectral class is A0V, making it a blue-tinged white main sequence star that is fusing hydrogen to helium in its core. He's a longtime member of NASA's Solar System Ambassadors program. His articles have appeared in numerous publications including Space.com, Sky & Telescope, Astronomy and Rolling Stone. Many people recognize its constellation, Lyra, as a triangle of stars connected to a parallelogram. All three stars are extremely bright in a region with few other bright stars. Vega was one of the stars used to define the magnitude scale, so it has an apparent magnitude around 0 (+0.026). Also, while Altair is 1½ times larger than Earth's sun, Vega is more than three times larger. The two lovers are placed in the sky, separated by the Celestial River or Milky Way. At about 500 million years, Vega is already middle-aged. Growing up in an astronomically wealthy family, Libby's parents, Erica and Miles, have absolutely astronomical careers and tons of money. When Vega is the pole star, a long exposure photograph would show stars circling it. Wega, less correctly Vega, originated in the Alfonsine Tables from the Waki of the Arabs, Bayer having both titles; Scaliger, Waghi; Riccioli, Vuega vel Vagieh; and Assemani, Veka. Conventional color descriptions are traditional in astronomy, and represent colors relative to the mean color of an A class star, which is considered to be white. Because it is more massive, Vega burns up its hydrogen fuel more quickly than our Sun, so its lifetime as a main-sequence star is only about one billion years, or about a tenth as long as the Sun's life. Let me get back to Vega though. If Vega was viewed from above one of its poles, it would appear round. Yes, to optical astronomers, \"color\"means something different than it does to mostordinary people.\"Color\" is defined asIn the most common example, the passbands are the Johnson-Cousins B and V. Consider severalstars in the constellation of Crux, the Southern Cross:Credit & Copyright: Greg Bock, Southern Astronomical SocietyClockwise from the bottom of the cross, they areHow can we interpret the color index?One way is to go back to the star Vega, the basis for the magnitude scale.Veg… Currently it is only about a tenth the age of our sun, and will run out of fuel in another half-billion years. In astronomer-speak, Vega is an “A0V main sequence star.” The “A0” signifies its temperature, whereas the “V” is a measure of energy output (luminosity), indicating that Vega is a normal star (not a giant). Vega is only about a tenth of the age of the Sun, but since it is 2.1 times as massive its expected lifetime is … Another factor also contributes to Vega’s brightness — the st… Vega will become a red giant about 650 million years in the future when it can no longer fuse … Larry Sessions has written many favorite posts in EarthSky's Tonight area. That is because Vega puts out more light; it is more luminous. Due to the higher period, Vega burn fuel at a rate much faster than our sun. At this time, no planet has been definitively identified orbiting Vega, but its possible terrestrial planets could orbit near the star, probably in its equatorial plane. Vega has a spectral class of A0V, which means it is a blue-white main-sequence star that fuses hydrogen to make helium. Orihime and her lover Hikoboshi meet on a bridge of magpies across the Celestial River, each year on the 7th night of the 7th moon. In China, the legend speaks of a forbidden romance between the goddess Zhinu – represented by Vega – and a humble farm boy, Niulang – represented by the star Altair. As an only child, Libby has always gotten what she wanted, though she never wanting anything. Vega has been one of the most important stars to humanity since ancient times because it is very bright and easily recognized by its blue color. The variety of colours of the stars is immediately obvious. Colours vary from bluish-white through to red. Its said that when Orpheus played this harp, neither god nor mortal could turn away. Based on the spectral type (A0Vvar) of the star, the star's colour is blue - white . Finder chart. You can also easily pick out its constellation Lyra, which is small and compact, and consists primarily of Vega and four fainter stars in the form of a parallelogram. Vega (Star) Color-magnitude diagram. Vega has been one of the most important stars to humanity since ancient times because it is very bright and easily recognized by its blue color. Here are the stars depicted in the illustration above, from Matthew Chin in Yuen Long, Hong Kong. Sirian: These souls come from the planets Sirius A and Sirius B. Sirius A is … His small book on world star lore, Constellations, was published by Running Press. In another 500 million years or so, Vega will become a class-M red giant, after which it will lose most of its mass and become a white dwarf. Red-band image from the Second Digitized Sky Survey (DSS2), measuring 30 arcminutes across. Vega is also known as Alpha Lyrae (α Lyrae, Alpha Lyr, α Lyr), as it is the principle star in the constellation Lyra, the lyre. Used with permission.
