带电扭曲黑洞的内部

Interior of a Charged Distorted Black Hole

Shohreh Abdolrahimi, Valeri P. Frolov, Andrey A. Shoom

摘要:

研究了带电非旋转扭曲黑洞的内部。我们考虑静态和轴对称的黑洞,并集中在一个特殊的情况下,带电的扭曲的解决方案时,得到的Harrison-Ernst变换从不带电的。我们证明了这种黑洞的柯西视界是正则的,只要在事件视界的畸变是正则的。研究了外视界和内视界的形状和内部几何。我们证明了视界的性质之间存在着对偶性。计算了在畸变黑洞内部沿对称轴自由降落的试验粒子的本征时间。我们还研究了视界间内域曲率的性质。发现了4D曲率不变量与外视界表面和内视界表面的高斯曲率之间的简单关系。

英文摘要:

We study interior of a charged, non-rotating distorted black hole. We consider static and axisymmetric black holes, and focus on a special case when an electrically charged distorted solution is obtained by the Harrison-Ernst transformation from an uncharged one. We demonstrate that the Cauchy horizon of such black hole remains regular, provided the distortion is regular at the event horizon. The shape and the inner geometry of both the outer and inner (Cauchy) horizons are studied. We demonstrate that there exists a duality between the properties of the horizons. Proper time of a free fall of a test particle moving in the interior of the distorted black hole along the symmetry axis is calculated. We also study the property of the curvature in the inner domain between the horizons. Simple relations between the 4D curvature invariants and the Gaussian curvature of the outer and inner horizon surfaces are found.
