A highly magnetized and rapidly rotating white dwarf as small as the Moon
White dwarfs represent the last stage of evolution of stars with mass less than about eight
times that of the Sun and, like other stars, are often found in binaries,. If the orbital period of …

General relativistic orbital decay in a seven-minute-orbital-period eclipsing binary system
General relativity predicts that short-orbital-period binaries emit considerable amounts of
gravitational radiation. The upcoming Laser Interferometer Space Antenna (LISA) is …

A rotating white dwarf shows different compositions on its opposite faces
White dwarfs, the extremely dense remnants left behind by most stars after their death, are
characterized by a mass comparable to that of the Sun compressed into the size of an Earth …

Minutes-duration optical flares with supernova luminosities
In recent years, certain luminous extragalactic optical transients have been observed to last
only a few days. Their short observed duration implies a different powering mechanism from …

SRGeJ045359. 9+ 622444: A 55 Minute Period Eclipsing AM Canum Venaticorum Star Discovered from a Joint SRG/eROSITA+ ZTF Search
Abstract AM Canum Venaticorum (AM CVn) systems are ultracompact binaries where a
white dwarf accretes from a helium-rich degenerate or semidegenerate donor. Some AM …
