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 ...

Astrophysicists have discovered the tightest ultracool dwarf binary system ever observed. The two stars are so close that it takes them less than one Earth day to revolve around each other. In other ...

Scientists have discovered a record-breaking binary star system consisting of two ultracool dwarf stars so close to each other that they complete an orbit in under a day. The binary system, designated ...

Astronomers have traced the origin of a colossal white dwarf to a catastrophic crash between two dead stars, turning a quiet ...

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 ...

A group of Brazilian astronomers observed a pair of celestial objects rarely seen in the Milky Way: a very low-mass white dwarf and a brown dwarf. What makes this binary system so unique is its origin ...

An international researcher team under the direction of Dr. Thorsten Nagel of the Institute for Astronomy and Astrophysics of the University of Tübingen recently discovered an unusual close binary ...
