论文摘要

在这项工作中,我们使用幂律宇宙学来调查在度量$ f(r)$重力的背景下的黑洞演变,以满足Starobinsky模型提供的条件。在我们的研究中,观察到目前可以通过这种综合模型来适当解释宇宙的膨胀,而无需暗能。我们还发现,黑洞的质量通过吸收重力的改变而吸收能量物质来减少,而更多的吸积率更多是质量损失。特别是在特定时间蒸发的黑洞,其形成质量接近$ 10^{20} $ gm及以上,无论其形成质量如何。同样,我们的分析表明,由公制$ f(r)$重力支撑的黑洞的最大质量为$ 10^{12} m _ {\ odot} $,其中$ m _ {\ odot} $代表太阳能质量。

In this work, we use power-law cosmology to investigate the evolution of black holes within the context of metric $f(R)$ gravity satisfying the conditions provided by Starobinsky model. In our study, it is observed that presently accelerated expansion of the universe can be suitably explained by this integrated model without the need for dark energy. We also found that mass of a black hole decreases by absorbing surroundings energy-matter due to modification of gravity and more the accretion rate more is mass loss. Particularly the black holes, whose formation masses are nearly $10^{20}$ gm and above, are evaporated at a particular time irrespective of their formation mass. Again our analysis reveals that the maximum mass of a black hole supported by metric $f(R)$ gravity is $10^{12} M_{\odot}$, where $M_{\odot}$ represents the solar mass.
