What is the metric for a black hole which is emitting Hawking radiation? Does it depend on previous history or does it depend only on the current mass of the black hole? Are there multiple known coordinate charts useful for working with such a metric?

  • $\begingroup$ Vaidya metric I guess. It's often used in analysis of evaporating back holes. $\endgroup$ Commented Sep 20, 2018 at 5:51
