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.
1 Αυγ 2017 · Three main evolutionary channels have been proposed for Binary Black hole (BBH) formation: (1) BBHs formed by isolated evolution of massive stellar binaries, (2) BBHs formed from tight binaries with fully mixed chemistry, and (3) BBHs formed by dynamical interaction in dense stellar clusters.
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.
30 Σεπ 2021 · Stellar-mass black holes — which weigh between a few and 100 times the mass of the Sun — speckle the universe. In our Milky Way alone, there are an estimated ten million to one billion...
3 Αυγ 2012 · We know how stellar black holes form: They are the remnants of massive stars, roughly 10 M☉ and above (6). Yet, how MBHs form and evolve inside galaxies is one of the most fascinating mysteries in modern astrophysics and one that astrophysicists seek to unravel through theoretical and observational work. How Do Massive Black Holes Form?
20 Σεπ 2021 · Observations reveal that astrophysical black holes come in two distinct families: stellar black holes, relics of massive stars, widespread in all galaxies of the Universe; and massive...
The formation of stellar BHs is of topical interest for several areas of astrophysics. Stellar BHs are remnants of massive stars, possible seeds for the formation of supermassive BHs, and sources of the most energetic phenomena in the universe, such as the gravitational waves produced by fusion of BHs.
