Astronomers from the University of Oklahoma and their colleagues report the detection of four white dwarf stars of a recently discovered rare DAQ spectral subclass. The newfound white dwarfs are slightly more massive than ...
Imagine the embers of a campfire, slowly dimming over time. That is the fate most stars in the universe face. After their nuclear fuel is spent, 98 percent of stars—including our sun—will eventually become white dwarfs. ...

Using ground-based telescopes, an international team of astronomers has observed a binary system containing at least one white dwarf, designated J0526+5934. The observational campaign has revealed that the binary is composed ...
Astronomers have conducted spectroscopic and photometric observations of a peculiar pulsating variable white dwarf known as TMTS J17184064+2524314. Results of the observational campaign, published January 26 on the preprint ...
In several billion years, our sun will become a white dwarf. What will happen to Jupiter and Saturn when the sun transitions to become a stellar remnant? Life could go on, though the giant planets will likely drift further ...

Astronomers from Turkey and Russia have performed optical observations of a magnetic cataclysmic variable known as SRGA J213151.5+491400. Results of the observational campaign, presented Jan. 11 on the pre-print server arXiv, ...
By investigating dwarf novae identified by the Zwicky Transient Facility (ZTF), astronomers have discovered four binary systems. The objects turned out to be eclipsing accreting ultracompact white dwarf binaries. The finding ...
