The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times ...

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.

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 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 ...

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 ...

The discovery that "vampire" white dwarfs spread dust brings astronomers closer to understanding the life and death cycle of stars. Astronomers have discovered a hitherto unknown source of the ...

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.

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.
