It's the definition of "no pain, no gain." The rapid spin of this white dwarf, that is vampirically taking stellar matter away from a companion star, could be explained by its shrinking radius.

Astronomers have made a first-of-its-kind discovery — a white dwarf star with two completely different faces. White dwarfs are burnt remains of dead stars. Our sun will become a white dwarf in ...

Scientists have discovered two rare white dwarfs—which are among the dimmest stars in the universe—that feature changes in their surface composition caused by magnetic fields. This brings the ...

Once the two stars get to the point of no return, mass will shift from one white dwarf to the other. That will initiate not one, but four explosions - a quadruple detonation. First, the star ...

One of the white dwarfs has a mass about 83 per cent that of our sun and the other about 72 per cent. No other known white dwarf binary has a larger combined mass, Munday said. "They are both ...

Our Sun will become a white dwarf in about 7 billion years. At that point, it will no longer produce energy through nuclear fusion, having exhausted its fuel (hydrogen and helium). Just like the ...

Eventually, the outer layers of the red giant will be blown away to leave behind a dense white dwarf no larger than a planet ... and a very large planet about 17 times the mass of Jupiter ...

A focused search will no doubt start to reveal the true population of planets around white dwarfs. If we find more Earth-similar worlds around white dwarfs, that opens up another pathway for ...

The observations made using the European Space Agency's XMM-Newton orbiting X-ray telescope appear to show a white dwarf nearing the point of no return - called the event horizon - as it orbits ...

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.

NASA is set to launch the Nancy Grace Roman space telescope no earlier than 2027, and it is expected to find many more planets through microlensing, including some around white dwarfs.
