摘要： Hawking radiation of scalar particles of Kerr-Newman-de Sitter XY (KNdSXY) black holes is studied by using complex analytical continuation (CAC) technique. We derive the surface gravity κh,κc and Hawking temperature Tb,Tc of the event horizons r+,r++. All of them are proportional to (|A|)1/2, where A is an indefinite multiple of KNdSXY metric.

Abstract: Hawking radiation of scalar particles of Kerr-Newman-de Sitter XY (KNdSXY) black holes is studied by using complex analytical continuation (CAC) technique. We derive the surface gravity $\kappa$h, $\kappa$c and Hawking temperature Tb, Tc of the event horizons r+, r++. All of them are proportional to (|A|)1/2, where A is an indefinite multiple of KNdSXY metric.
