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 ...

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 ...

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 ...

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, ...

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 ...
