An international team of astronomers reports the discovery of a new cataclysmic variable. The newfound system, designated SRGeJ041130.3+685350 (or SRGeJ0411 for short), has an orbital period of about ...

Using NASA's Swift spacecraft, astronomers have discovered a new cataclysmic variable (CV) through its ultraviolet (UV) bursting activity. The newfound CV, designated TUVO-21acq, was detected as part ...

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, ...

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 ...

The new technique depends on disturbances in the material being fed from one star to another as a third body orbits a binary pair. When you purchase through links on our site, we may earn an affiliate ...

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 ...

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 ...
