Primordial black hole: Mass and angular momentum evolution

  • G. S. Bisnovatyi-KoganEmail author

The evolution of a primordial low-mass black hole (PBH) in a hot universe is considered. The PBH mass increase and spin decrease due to accretion of radiation-dominated matter are estimated using the results of a numerical simulation of PBH formation and approximate relations for accretion to a rotating black hole.
