Beyond Hawking evaporation of black holes formed by dark matter in compact stars

Year: 2025

Type: article

Abstract: The memory burden effect is an explicit resolution to the information paradox by which an evaporating black hole acquires quantum hair, which then suppresses its rate of mass loss with respect to the semiclassical Hawking rate. We show that this has significant implications for particle dark matter that captures in neutron stars and forms black holes that go on to consume the host star. In particular, we show that constraints on the nucleon scattering cross section and mass of spin-0 and spin- 1 / 2 dark matter would be extended by several orders of magnitude.
