WASHINGTON (Reuters) -Astronomers have spotted two hefty white dwarf stars - highly compact stellar embers - orbiting close together that appear destined to die in an extraordinarily violent quadruple ...

White dwarf stars represent the evolutionary endpoints of medium- and low-mass stars, comprising the dense, electron-degenerate cores left after nuclear fuel exhaustion. In binary systems, ...

A nova is a relatively small surface explosion from a white dwarf below the Chandrasekhar limit of 1.4 solar masses. Novae can recur on timescales as short as a year. Large telescopes have been around ...

It’s not only professional astronomers who make amazing discoveries about space — sometimes enthusiastic amateurs can make impressive scientific discoveries as well. Recently citizen scientist Frank ...

A very interesting binary star system subbed AR Scorpii some 380 light years away from our planet contains both a red dwarf and a white dwarf, but the qualities of this binary system in particular are ...
