论文摘要
黑洞产生的潮汐力是与时空曲率张量有关的一般相对性的重要结果。在潮汐力的天体物理含义中，揭示了潮汐破坏事件。我们分析了带电的海沃德常规黑洞的时空中的潮汐力，获得了潮汐张量和地球偏差方程的成分。我们发现，与Schwarzschild时空不同，径向和角度的潮汐力可能会消失和改变迹象。我们注意到，在这个常规的黑洞时空中，潮汐力在径向坐标的起源处是有限的。我们获得了由两个不同初始条件的黑洞粉尘插入的尘埃构成的人体偏差载体。
Tidal forces produced by black holes are an important result of General Relativity, related to the spacetime curvature tensor. Among the astrophysical implications of tidal forces, stands out tidal disruption events. We analyze the tidal forces in the spacetime of an electrically charged Hayward regular black hole, obtaining the components of the tidal tensor and the geodesic deviation equation. We find that the radial and angular tidal forces may vanish and change sign, unlike in the Schwarzschild spacetime. We note that tidal forces are finite at the origin of the radial coordinate in this regular black hole spacetime. We obtain the geodesic deviation vector for a body constituted of dust infalling towards the black hole with two different initial conditions.
