Energy and Angular Momentum of a Dilaton Black Holes, Revista Mexicana de Astronomía y Astrofísica, 44

By  and Marcelo Samuel Berman and Marcelo Samuel Berman


Following a prior paper, we review the results for the energy and angular momentum of a Kerr-Newman black hole, and then calculate the same properties for the case of a generalised rotating dilaton of the type derived, without rotation, by Garfinkle, Horowitz, and Strominger (1991; 1992). We show that there is, as far as it refers only to the energy and angular momentum, an interaction among the fields, so that, the gravitational and electromagnetic fields may be obscured by the strength of the scalar field. (Spanish) Dando seguimiento a un artículo previo, revisamos los resultados para la energía y momento angular de un hoyo negro de Kerr-Newman, y extendemos el calculo para el caso de un dilaton en rotación, obtenido a partir del modelo de Garfinkle, Horowitz, y Strominger (1991; 1992). Mostramos que hay, en lo que se refiere solamente a la energía y momento angular, una interacción entre los campos, de forma que, el gravitacional y el electromagnetico, puedem ser ocultados por la intensidad del campo escalar
