广义相对论中幻影黑洞度规的能量动量分布

Energy-Momentum Distribution in General Relativity for a Phantom Black Hole Metric

P. K. Sahoo, I. Radinschi, K. L. Mahanta

摘要:

我们利用广义相对论中的Møller和Landau-Lifshitz能量动量定义来计算幻影黑洞时空的能量动量分布。幻影黑洞模型被应用于银河系中心的超大质量黑洞。我们得到,在这两种赝张量中,能量分布依赖于黑洞的质量$M$、幻影常数$p$和径向坐标$r$ .此外,所有计算的动量被发现是零。限制性病例$r\rightarrow 0$、$r\rightarrow \infty $和$r\rightarrow -\infty $也是本研究的主题。

英文摘要:

We use the Møller and Landau-Lifshitz energy-momentum definitions in General Relativity (GR) to evaluate the energy-momentum distribution of the phantom black hole space-time. The phantom black hole model was applied to the supermassive black hole at the Galactic Centre. We obtain that in both pseudotensorial prescriptions the energy distribution depends on the mass $M$ of the black hole, the phantom constant $p$ and the radial coordinate $r$. Further, all the calculated momenta are found to be zero. The limiting cases $r\rightarrow 0$, $r\rightarrow \infty $ and $r\rightarrow -\infty $ have also been the subject of the study.
