University of Warwick astronomers have discovered an extremely rare, high-mass, compact binary star system only ~150 light ...

Learn how gravity and mass are pulling two stars into tighter, faster orbit around each other, with an explosive collision ...

When they reach the end of their long evolutions, smaller stars—those up to eight times as massive as our own sun—typically become white dwarfs. These ancient stars are incredibly dense.

leaving behind a small dim star at its center known as a white dwarf, explains the Chandra X-ray Center (CXC) explains. "We might have finally found the cause of a mystery that's lasted over 40 ...

The search for habitable planets has taken a leap forward with new space telescopes probing exoplanet atmospheres for life. The James Webb Space Telescope (JWST) has begun analyzing distant worlds, ...

A white dwarf is the stellar core left behind after a dying star has exhausted its nuclear fuel. A new study used data from powerful X-ray missions, NASA’s Chandra X-ray Observatory and the Euro ...

An international team of astronomers led by Dr Iris de Ruiter, now at the University of Sydney, has shown that a white dwarf and a red dwarf star orbiting each other every two hours are emitting ...

Nova explosions occur in semi-detached binary systems containing a cool late-type star and a white dwarf. "A hot white dwarf star, about the size of the Earth but having mass comparable with that ...

Pairing the known age of a white dwarf with the variable age of a main sequence star allows for more straightforward calculations of important parameters like the relationship between a star's age ...
