论文摘要
Kerr-Vaidya指标是Kerr指标最简单的非平稳扩展。我们探索了它们的特性,并将它们与球形对称的自洽溶液的近水压限制(Ingoing vaidya指标,质量减少,质量增加,质量增加),以蒸发和增强物理黑色孔。 Newman-Janis转型将相应的Vaidya和Kerr-Vaidya指标联系起来。对于非零角动量,能量张量违反了无效的能量条件(NEC)。但是,我们表明其结构与NEC侵略张量的标准形式不同。即将离任的Kerr-Vaidya公制的明显视野与Kerr Black Hole的视野相吻合。对于Ingoing指标,其位置不同。我们为该表面得出了普通的微分方程,并以数值定位。球形对称积聚的黑洞会导致防火墙 - 插入的观察者感知到的分歧能量密度,压力和通量。我们证明,对于即将离任的Kerr-Vaidya指标也是如此
Kerr-Vaidya metrics are the simplest nonstationary extensions of the Kerr metric. We explore their properties and compare them with the near-horizon limits of the spherically symmetric self-consistent solutions (the ingoing Vaidya metric with decreasing mass and the outgoing Vaidya metric with increasing mass) for the evaporating and accreting physical black holes. The Newman-Janis transformation relates the corresponding Vaidya and Kerr-Vaidya metrics. For nonzero angular momentum, the energy-momentum tensor violates the null energy condition (NEC). However, we show that its structure differs from the standard form of the NEC-violating tensors. The apparent horizon in the outgoing Kerr-Vaidya metric coincides with that of the Kerr black hole. For the ingoing metric, its location is different. We derive the ordinary differential equation for this surface and locate it numerically. A spherically symmetric accreting black hole leads to a firewall -- a divergent energy density, pressure, and flux as perceived by an infalling observer. We show that this is also true for the outgoing Kerr-Vaidya metric
