Technically, the sun is a G-type main-sequence star — specifically, a G2V star. The "V" indicates that it is a dwarf, Tony Wong, a professor of astronomy at the University of Illinois Urbana-Champaign ...

Earth exoplanets orbiting M-dwarf stars, identifying specific candidates that may have retained detectable atmospheres.

In addition, astrophysical observations had revealed that occasionally, white dwarfs would cool off way faster than expected.

Astronomers may have finally solved the mystery of how superdense dead stars called white dwarfs keep their heavy metal shells fresh — by cannibalizing what remains of their planetary systems. White ...

Astronomers have traced the origin of a colossal white dwarf to a catastrophic crash between two dead stars, turning a quiet ...

Hubble spots white dwarf star 'snacking' on chunk of Pluto-like object. The NASA/ESA Hubble Space Telescope has spotted a ...

"While white dwarf stars may still give off some heat from residual nuclear activity in their outer layers, they no longer exhibit nuclear fusion at their cores. For this reason, not much ...

In a paper published today in Nature, scholars from the Institute for Advanced Study; the University of Victoria, Canada; and the University of Warwick, U.K., have proposed a new theory that explains ...

Dark matter remains one of science's deepest mysteries. It makes up about 25% of our universe, yet scientists only observe its gravitational effects. Although invisible, researchers continue searching ...

Red dwarf stars make up the largest population of stars in the galaxy, but they hide in the shadows, too dim to be seen with the naked eye from Earth. Their limited radiance helps to extend their ...

An international team of astronomers led by Dr Iris de Ruiter, now at the University of Sydney, has shown that a white dwarf and a red dwarf star orbiting each other every two hours are emitting radio ...

The event occurred at the edge of the Milky Way. — -- Astronomers have uncovered evidence that a white dwarf may have gone into death star mode on the edge of the Milky Way, shredding a planet ...
