General relativistic rotational energy extraction from black holes-accretion disk systems
D. Pugliese,
Z. Stuchlik
Abstract:The determination of mass and spin parameters of the black holes (BHs) is crucial in the analysis of the merger of BHs and BHs formation and evolution, including accretion. Here we constrain the BH spin with the evaluation of the dimensionless parameter ξ representing the total rotational energy extracted versus the mass of the BH, following procedure introduced in [1] that is independent from the details of the specific extraction process. The energy extraction can power an outflow which can be then observed.… Show more
