Kiselev black holes in f ( R , T ) gravity

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.
