标题： Rotating black hole in Rastall theory

摘要： TO_BE_TRANSLATED: We discuss spherically symmetric exact black hole solution in the context of Rastall theory, and in turn present rotating black hole solution which generalize the Kerr-Newman solution. Interestingly, for a given value of Rastall parameter $\lambda$, there exists a critical rotation parameter $a_E$ which corresponds to an extremal black hole with degenerate horizons. We calculate the thermodynamical quantities associated for the rotating black hole. The particle motion is also analysed and behaviour of effective potential is discussed. 显示英文摘要
