White dwarfs (blue-white) are very cool for stars Mark A. Garlick
A strangely cool star absorbed its planets billions of years before Earth even existed.
Last year, astronomers https://www.newscientist.com/article/2292158-weird-white-dwarf-that-is-colder-than-it-should-be-defies-explanation/”>spotted a white dwarf star about 90 light years from us. White dwarfs are the remnants of dead stars that have ceased to carry out nuclear fusion, but this one, WD J2147-4035, appeared to be much cooler than most white dwarfs. Its relatively cold temperature indicated that it was about 10 billion years old – much older than other stars in its galactic neighbourhood.
