#White Dwarf

Astronomers have recorded history's first second-generation planet born from the ashes of the white dwarf HS 0209+0832 due to a unique chemical composition.

A new study by astronomers has shown that the outer Solar System may collapse just a billion years after the Sun becomes a white dwarf due to asymmetric mass ejections.

Astronomers have identified the nature of the radio signals from ASKAP J1745-5051, which had remained unexplained for nearly 20 years: a close binary system of a white and a red dwarf generates bursts through the interaction of ultra-powerful magnetic fields.

Astronomers recorded one of the most powerful repetitive nova explosions, LMC68, in the Large Magellanic Cloud. Spectra revealed anomalously hot gas and silicon shining 95 times brighter than the Sun.
