A first ever detection of a coronal mass ejection from a small red dwarf could have big consequences for life on any nearby ...

Some white dwarfs in rapid binary orbits are far hotter and larger than theory predicts. Researchers found that powerful tidal forces between them generate enough heat to inflate their sizes and ...

For the first time ever, astronomers have spotted a powerful coronal flare (cme) from a star other than the Sun.

Astronomers recently peered deep into space and found that an old, faint white dwarf named LSPM J0207+3331, located about 145 light-years away, is still consuming the rocky remains of its former ...

Hubble Space Telescope observations of white dwarf star G238-44 has shown that it is "consuming both rocky-metallic and icy ...

Imaging shows NGC 6789 building stars in near-total isolation, pushing scientists to rethink gas supply and formation in ...

White dwarf stars represent the evolutionary endpoints of medium- and low-mass stars, comprising the dense, electron-degenerate cores left after nuclear fuel exhaustion. In binary systems, ...

New research has shed doubt upon the nature of a distant "dead star" that exists in a binary system with an active stellar companion. Scientists behind the research think this stellar corpse is ...

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 ...
