Kerr时空描述的旋转物体的准局域能量

Quasi-Local Energy of a Rotating Object Described by Kerr Spacetime

Bjoern S. Schmekel

摘要:

用直接计算的方法计算了用克尔度规描述并被固定半径表面包围的旋转黑洞的布朗约克准局域能量。没有对角动量或Boyer-Lindquist坐标中的径向坐标进行特殊假设。任意参考项已设置为零。这一结果可能与天体物理学中的应用、基本粒子的建模或准局域量框架的扩展有关。给出了不完全椭圆积分的解析表达式。

英文摘要:

The Brown-York quasi-local energy of a rotating black hole described by the Kerr metric and enclosed by a fixed-radius surface is calculated by direct computation. No special assumptions on the angular momentum or the radial coordinate in Boyer-Lindquist coordinates were placed. The arbitrary reference term has been set to zero. The result may be relevant for applications in astrophysics, for modeling elementary particles or for extensions of the framework of quasi-local quantities. An analytic expression in terms of incomplete elliptic integrals is given.
