Dynamics of Particles Around a Regular Black Hole with Nonlinear Electrodynamics

引用

Communications in Theoretical Physics 2016年第11期65卷 509-516页

作者： Abdul jawad Farhad Ali Mubasher Jamil Ujjal Debnath Department of Mathematics COMSATS Institute of Information Technology Department of Mathematics Kohat University of Science and Technology Department of Mathematics School of Natural Sciences (SNS) National University of Sciences and Technology (NUST) Department of Mathematics Indian Institute of Engineering Science and Technology

We investigate the dynamics of a charged particle being kicked off from its circular orbit around a regular black hole by an incoming massive particle in the presence of magnetic field. The resulting escape velocity, escape energy and the effective potential are analyzed. It is shown that the presence of even a very weak magnetic field helps the charged particles in escaping the gravitational field of the black hole. Moreover the effective force acting on the particle visibly reduces with distance. Thus particle near the black hole will experience higher effective force as compared to when it is far away.
