This black hole, detected using an observatory in Chile, is minding its manners and has not shredded its two partners: stars about five or six times the mass of the sun. At least not yet.
“The formation of a black hole is a violent process, and most models would not have predicted a triple system could survive that but rather would fly apart,” Rivinius said.
The black hole forms a pair with one of the two stars, as near to one another as the Earth is to the sun. The other star is much further away, orbiting the pair. This star spins so rapidly that it is misshapen, bulging at the equator.
The two stars are sufficiently distant from the black hole that it is not pulling material from them. But in a few million years the closer star is expected to grow in size as part of its life cycle.
“What happens then is uncertain,” Rivinius said. “The most spectacular outcome would be if the black hole ends up with that star inside it.”
