The new infrared image from the NASA/ESA/CSA James Webb Space Telescope reveals the complex structure of gas and dust shed by a white dwarf in the center...
Using ESO’s Very Large Telescope (VLT), astronomers have captured a breathtaking shock wave around the white dwarf star 1RXS J052832.5+283824 (RXJ0528+2838...
White dwarfs are the dense cores left behind when stars exhaust their fuel and collapse. They are Earth-sized stellar embers weighing typically half as...
In a 2023 paper, Professor Heino Falcke and his colleagues at Radboud University showed that not only black holes, but also all other objects in the Universe...
Astrophysicists have found that a recently-discovered transient radio source, ILT J110160.52+552119.62, whose roughly minute-long pulses arrive with a...
Astronomers may finally have settled the question of what is causing highly energetic X-rays from WD 2226-210, a white dwarf star located at the center...
White dwarfs may present amenable environments for life on planets formed within or migrated to their habitable zones, generating warmer surface environments...
Using a catalog of 26,041 white dwarfs observed by the Sloan Digital Sky Survey, astronomers have confirmed a long-predicted effect in these ancient ultradense...
A neutron star in the X-ray binary system 4U 1820-30 spins 716 times per second, making it one of the fastest-spinning objects ever observed, according...
Astronomers using the NASA/ESA Hubble Space Telescope have made a unique timelapse of R Aquarii’s dynamic behavior from observations spanning from 2014...
Astronomers using the Keck II 10-m telescope have discovered evidence for an Earth-mass planet and a brown dwarf orbiting a white dwarf star. The planet...
With an estimated distance of 140 parsecs (457 light-years), the L-subdwarf star CWISE J124909+362116.0 (J1249+36 for short) has a total speed of at least...
Astronomers have proposed a new theory that explains why a puzzling population of white dwarf stars stopped cooling for at least eight billion years.
This...
Dynamically active planetary systems orbit a significant fraction of white dwarf stars. These stars often exhibit surface metals accreted from debris disks....
WD 0032-317B, a brown dwarf orbiting around the hot, low-mass white dwarf WD 0032-317, is estimated to have a surface temperature of about 8,000 K and...
ZTF J203349.8+322901.1, nicknamed Janus after the two-faced Roman god of transition, is a transitioning white dwarf with two faces: one side of its atmosphere...
White dwarf pulsars include a rapidly spinning, burnt-out stellar remnant called a white dwarf, which lashes a companion red dwarf with powerful beams...
The detection of the Type Ia supernova SN 2020eyj at radio wavelengths show that the exploded white dwarf had a helium-rich companion.
An artist’s rendition...
Supernova (SN) 185 occurred in 185 CE in the direction of Alpha Centauri, between the constellations of Circinus and Centaurus, and remained visible to...
