White dwarfs are among the most compact objects in the cosmos, though not as dense as a black hole. Stars with up to eight times the mass of our sun appear destined to end up as a white dwarf.

If the hypothetical object orbiting the black hole were a white dwarf, the undead star would be in some sort of tidal limbo, where it would be “starting to get ripped apart a little bit,” she ...

According to the research, the strange behavior of 1ES is caused by a 'white dwarf' that came very close to the black hole. A white dwarf is the remains of a dead star and is made up of matter ...
