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 ...

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 ...

Jackson Ryan was CNET's science editor, and a multiple award-winning one at that. Earlier, he'd been a scientist, but he realized he wasn't very happy sitting at a lab bench all day. Science writing, ...

With the aid of citizen scientists, astronomers have discovered an erupting cataclysmic variable star in a rarely seen ...

Scientists have discovered a pair of stars locked in an incredibly close orbit that circle each other once every 51 minutes - and according to the results of a new study, they are only going to speed ...

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 ...

Nearly half the stars in our galaxy are solitary like the sun. The other half comprises stars that circle other stars, in pairs and multiples, with orbits so tight that some stellar systems could fit ...

LOS ANGELES - Some might complain over a lack of excitement in our solar system but a recent discovery by MIT astronomers reminds us why we should be grateful for a "boring" location among the stars.

Astronomers have discovered a stellar binary, or pair of stars, with an extremely short orbit, appearing to circle each other every 51 minutes. The system seems to be one of a rare class of binaries ...
