Abstract

In this study, we explore the tidal effects within the spacetime of a magnetically charged black hole. Our investigation reveals that increasing the magnetic charge leads to a decrease in the radial tidal effect, contrasting with the behavior observed in the angular tidal force. Additionally, we find that the sign of the tidal force’s radial and angular components alternates between the event horizon and the Cauchy horizon. Furthermore, by solving the geodesic divergence equation for two distinct initial conditions of radially free-falling entities toward the black hole, we derive the geodesic divergence vector. These findings contribute to our understanding of the gravitational dynamics in magnetically charged black holes.
磁带电黑洞时空中的潮汐动力学和测地线散度
在这项研究中,我们探索了一个带磁性的黑洞在时空中的潮汐效应。我们的研究表明,增加磁荷会导致径向潮汐效应的减弱,这与在角潮汐力中观察到的行为相反。此外,我们发现潮汐力的径向和角分量的符号在事件视界和柯西视界之间交替。此外,通过求解径向自由落体向黑洞的两种不同初始条件下的测地线散度方程,导出了测地线散度向量。这些发现有助于我们理解磁化黑洞的引力动力学。

期刊介绍: High Energy Density Physics is an international journal covering original experimental and related theoretical work studying the physics of matter and radiation under extreme conditions. ''High energy density'' is understood to be an energy density exceeding about 1011 J/m3. The editors and the publisher are committed to provide this fast-growing community with a dedicated high quality channel to distribute their original findings. Papers suitable for publication in this journal cover topics in both the warm and hot dense matter regimes, such as laboratory studies relevant to non-LTE kinetics at extreme conditions, planetary interiors, astrophysical phenomena, inertial fusion and includes studies of, for example, material properties and both stable and unstable hydrodynamics. Developments in associated theoretical areas, for example the modelling of strongly coupled, partially degenerate and relativistic plasmas, are also covered.
