CVs are binary star systems comprising a white dwarf and a normal star companion. They irregularly increase in brightness by a large factor, then drop back down to a quiescent state. Polars are a ...

Astronomers from Turkey and Russia have performed optical observations of a magnetic cataclysmic variable known as SRGA J213151.5+491400. Results of the observational campaign, presented Jan. 11 on ...

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, ...

A team of astronomers has identified a new polar cataclysmic variable, a rare type of binary star system featuring a highly ...

In yet another discovery, astronomers at MIT and elsewhere have found a pair of stars that has the shortest orbital period yet discovered. The star circles each other every 51 minutes. Astronomers dub ...

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 ...

Cataclysmic variable stars are compact binary systems in which a white dwarf accretes material from a close companion, typically a late-type main-sequence star. The accreted matter forms a disc unless ...

Optical observations obtained using the Southern Astrophysical Research ( SOAR) Telescope showed a white dwarf binary at the ...
