Latest Stellar classification Stories
Astronomers have snapped a very detailed image of the outer atmosphere of the red supergiant Betelgeuse.
A team of astronomers, led by Hugues Sana of the University of Amsterdam, has observed a binary star that potentially weighed 300 to 400 times the mass of our Sun at its birth.
ESA scientists have recently discovered that neighbor star Alpha Centauri A displays some of the same bizarre temperature phenomena as our Sun and may help to solve a long-standing solar mystery.
There are small subsets of stars among the hundred billion in the Milky Way called ultra-cool dwarfs, which have a temperature below 2500 Kelvin.
A new image released by the European Space Agency shows multiple arcs around Betelgeuse, the nearest red supergiant star to Earth.
By using the Hubble and Spitzer space telescopes, NASA officials say they have managed to complete the most detailed weather map to date for the cool, planet-like stars known as brown dwarfs.
An international team of astronomers have discovered a unique and exotic star system with a very cool methane-rich (or T-) dwarf star and a â€˜dyingâ€™ white dwarf stellar remnant in orbit around each other.
Data from NASA's Galaxy Evolution Explorer spacecraft may force astronomers to discard the assumption that stars of certain sizes form in certain quantities. For decades, astronomers have believed the proportion of small to big stars was fixed.
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....
