Cataclysmic variables (CVs) are close binary systems in which a white dwarf accretes material from a companion star, typically a low‐mass, main-sequence star. The accretion process, often mediated by ...

White dwarfs are the compact remnants of stars that have stopped nuclear burning, a fate that will eventually befall our sun.

Dwarf novae are a prominent subclass of cataclysmic variables; binary star systems in which a white dwarf accretes matter from a donor star. This accretion process drives episodic outbursts due to ...

Old binary star systems may contain stars that are even hotter than scientists previously believed. White dwarfs are the dense, compact remains left behind when stars exhaust their nuclear fuel, a ...

a white dwarf and a red dwarf in very close proximity didn’t have much to go on. Just five years ago, scientists knew of fewer than 100 such systems, called pre-cataclysmic variables. But today a team ...

Within six months, Kilonova Seekers’ over 2,000 volunteers contributed more than 600,000 classifications to researchers, resulting in a total of 20 new discoveries. Now, astronomers have announced the ...
