Stellar-Mass Black Hole

Cosmology & UniverseEstablished Science

Definition

A black hole of a few to a few dozen solar masses, formed when a massive star collapses.

Scientific overview

When a massive star exhausts its fuel, its core can collapse past the neutron-star limit into a stellar-mass black hole. These are detected in X-ray binaries and, since 2015, through the gravitational waves emitted when two of them merge.
