One is a hypothetical white dwarf that's passed through much of its life cycle and is on a slow path to stellar death. The other subject is Kepler-62, a "main sequence" star at a similar phase in ...

The authors found that the region in which an exoplanet could host life-supporting liquid water was much closer to the white dwarf star than the same zone around Kepler-62.

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.

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 ...

Why this 'teenage vampire' white dwarf has scientists so excited. ... Main sequence stars: definition & life cycle. References. By Ben Biggs, Nola Taylor Tillman last updated 26 September 2022 ...

For the study, the researchers used computer models to compare Earth-like exoplanets each orbiting a white dwarf star and the main-sequence K-dwarf star, Kepler-62, both of which exhibit temperatures ...

European Southern Observatory’s Very Large Telescope took photos a rare supernova roughly 300 years after it happened ...

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.

Washington: 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.
