标题： Accretion and Evaporation of Modified Hayward Black Hole

摘要： 首先我们假设了最广义的静态球对称黑洞度规。 已经研究了任意一般类型的流体绕黑洞吸积的情况。 分析了修正后的Hayward黑洞周围流体流动的吸积，并且随后计算了吸积过程中的临界点、流体四速度和声速。 此外，在考虑黑洞蒸发（即霍金辐射）的情况下，分析了吸积过程中黑洞动力学质量的变化情况。 显示英文摘要

摘要： First we have assumed the most general static spherically symmetric black hole metric. The accretion of any general kind of fluid flow around the black hole have been investigated. The accretion of fluid flow around the modified Hayward black hole have been analyzed and we then calculated the critical point, fluid 4 velocity and velocity of sound during accretion process. Also the nature of the dynamical mass of black hole during accretion of fluid flow and taking into consideration of Hawking radiation from black hole i.e., evaporation of black hole have been analyzed.
