Stellar black hole - Wikipedia
A stellar black hole (or stellar-mass black hole) is a black hole formed by the gravitational collapse of a star. [1] They have masses ranging from about 5 to several tens of solar masses. [2] They are the remnants of supernova explosions, which may be observed as a type of gamma ray burst. These black holes are also referred to as collapsars.

Astronomers generally divide black holes into three categories according to their mass: stellar-mass, supermassive, and intermediate-mass. The mass ranges that define each group are approximate, and scientists are always reassessing where the boundaries should be set.

Hunting for and characterizing stellar mass black holes, which can include information about their birth process and evolution. Black holes come in three categories: Stellar Mass Black Holes are born from the death of stars much more massive than the Sun.
Most massive stellar black hole in our galaxy found | ESO
2024年4月16日 · Astronomers have identified the most massive stellar black hole yet discovered in the Milky Way galaxy. This black hole was spotted in data from the European Space Agency’s Gaia mission because it imposes an odd ‘wobbling’ motion on the companion star orbiting it.
