We compute, using quantum field theory in curved spacetime at the tree level, the power emitted by the rotating charge minimally coupled to the Maxwell field. We also compute how much of the radiation emitted by the swirling charge is absorbed by the black hole.engAcesso AbertoBuraco negroBuraco negro de SchwarzschildCarga elétricaCampo quânticoCampo MawellRadiação eletromagnéticaElectric charge rotating around a black holeArtigo de Periódico
