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.

Astronomers have discovered a "missing link": a tiny black hole lurking with a red giant star in a strange and difficult-to-explain binary system.

A black hole infamous for strange features has once again baffled astronomers, this time with rapid X-ray flashes. What could they be?

It's a dead star called a " white dwarf." "This would be the closest thing we know of around any black hole," Megan Masterson, a physicist at MIT who co-led the research, said in a statement.

Astronomers Found Strange, Accelerating X-Ray Pulses Coming From a Black Hole. They Might Be a Sign of an Orbiting White Dwarf The dense stellar remnant would, if confirmed, be the closest known ...

Gravity then causes them to collapse and blow off their outer layers in a "red giant" stage, eventually leaving behind a compact core roughly the diameter of Earth - the white dwarf.

The weird outbursts of a distant supermassive black hole may be caused by a death-defying white dwarf walking a cosmic tight rope around it.

The researchers estimated that the white dwarf is orbiting the black hole at about 5% the distance that separates Earth from the sun, or a bit under 5 million miles (8 million km).
