自旋粒子在暗物质晕环绕的类克尔黑洞中的运动
Spinning Particle Motion around Kerr-like Black Hole Surrounded by the Dark Matter Halo
摘要
Abstract
Investigations were conducted on the gravitational dynamical properties of Kerr-like black holes surrounded by dark matter halos,with a focus on examining the influence of dark matter halos on the motion of spinning particles.The Mathisson-Papapetrou-Dixon(MPD)equation combined with the Tulczyjew spin supplementary condition(SCC)was employed to derive the effective potential of spinning particles,and the physical characteristics of their innermost stable circular orbit(ISCO)were analyzed.The results indicated that as the density and radius of the dark matter halo increased,both the orbital radius and angular momentum of the spinning particles' ISCO exhibited a monotonically increasing trend;in contrast,the energy showed significant non-monotonic variation characteristics:it first decreased with the increase of dark matter halo parameters,reached a minimum value,and then rose gradually.The research findings deepened the understanding of the gravitational interaction mechanism between black holes and dark matter halos,providing a theoretical basis for comprehending their complex dynamical processes.关键词
