摘要:

我们获得新的精确解的引力场方程的背景下,$f(R,T)$重力,从而获得不同类别的黑洞包围的流体,考虑到一些特定的值的状态方程的参数,$w$。为了获得这些解决方案的背景下,$f(R,T)$重力,我们认为可行的特定选择的$f(R,T)$。考虑到各向异性的能量动量张量,我们写出了这种类型的解决方案所需的对称性的场方程。然后,我们分析了一般的能量条件,也为状态方程的参数$w$的特定值。此外,热力学量,如霍金温度和质量相关联的解决方案的视野,考虑在我们的分析。

英文摘要:

We obtain new exact solutions for the gravitational field equations in the context of $f(R,T)$ gravity, thereby obtaining different classes of black holes surrounded by fluids, taking into account some specific values of the parameter of the equations of state, $w$. In order to obtain these solutions in the context of $f(R,T)$ gravity, we consider viable particular choices of the $f(R,T)$. Considering an anisotropic energy-momentum tensor, we write the field equations with the required symmetries for this type of solution. Then, we analyze the conditions of energy in a general way and also for particular values of the parameter $w$ of the equation of state. In addition, thermodynamic quantities, such as Hawking temperature and mass associated to the horizons of solutions, are taken into account in our analysis.
