Latest Stellar classification Stories
A team of astrophysicists and computational astronomers have discovered why sibling stars look alike – those formed from a single cloud share the same chemical fingerprint due to early, fast and turbulent mixing of gas in the giant molecular clouds where star formation occurs.
Being hailed as a critical first step in a massive attempt to map the Milky Way, a team of European astronomers has devised a novel way to categorize stars based on their metallic composition
Researchers from University College London and the University of New South Wales have reportedly developed a new, more powerful and more accurate way to detect extraterrestrial life that focuses on methane.
In a discovery decades in the making, scientists have detected the first of a “theoretical” class of stars first proposed in 1975 by physicist Kip Thorne and astronomer Anna Żytkow.
NASA's WISE and Spitzer Space Telescope have discovered what appears to be the coldest "brown dwarf" known -- a dim, star-like body that, surprisingly, is as frosty as Earth's North Pole.
Astronomers using the European Southern Observatory’s (ESO) Very Large Telescope have discovered the largest yellow star so far. The discovery is of a yellow hypergiant star located about 12,000 light years away.
Most brown dwarfs may contain storms as big as Jupiter’s “Great Red Spot,” according to findings presented at the American Astronomical Society in Washington.
Two years ago NASA scientists revealed a new class of stars, dubbed ‘Y dwarfs’, thought to be about as warm as the human body. However, newly published research indicates that these cold stars are probably a bit warmer than the boiling point of water.
Researchers at Vanderbilt University have found a clever, simple way to accurately estimate stellar gravity using the star's flickering variations of light.
Astronomers have snapped a very detailed image of the outer atmosphere of the red supergiant Betelgeuse.
Star -- A star is a self-gravitating sphere of plasma in hydrostatic equilibrium that generates energy in its interior through the process of nuclear fusion. Energy from this process radiates into space as electromagnetic radiation and neutrinos. Star formation and evolution As learned by star formation astronomers, stars are born in molecular clouds, regions of higher density of matter, and form by gravitational instability inside those clouds. High mass stars illuminate powerfully...
Vega -- Vega (Alpha Lyrae) is the lead star in the constellation Lyra, reaching near directly overhead the mid-northern latitudes, during the summer. It's a "nearby star" at only 25 light years distant and together with Arcturus and Sirius, one of the brightest stars in the Sun's neighbourhood. Vega is a vertex of the Summer Triangle. Its spectral class is A0V (Sirius, an A1V, is slightly less powerful) and it's firmly in the main sequence, fusing hydrogen to helium in its core....
