About 8,150 light-years from Earth, a white dwarf star named Gaia22ayj has intrigued astronomers. Its unusual behavior, ...

The team eventually concluded that Gaia22ayj is a missing link in the life cycle of white dwarf pulsars, a rare and short-lived early phase of these objects.

Eventually, a main sequence star burns through the hydrogen in its core, reaching the end of its life cycle. ... White dwarfs no longer burn fusion at their center, but they still radiate heat.

A slowly cooling stellar ember called a white dwarf with a scar on its face is providing new insight into the behavior of certain "cannibal" stars at the end of their life cycle.

For years, researchers thought white dwarfs' dynamic temperature decrease made their atmospheres too unstable for life. However, as the James Webb Space Telescope begins to document white dwarfs ...

White dwarf planets, remnants of dying stars, might surprisingly sustain life in their habitable zones for billions of years. A new study explores their potential as cosmic cradles for evolution.
