Accretions of (m, n)-type Pilgrim dark energies with logarithmic and power-law entropy corrections onto (D + 2)-dimensional black hole and wormhole

Abstract

This work aims to study the accretions of dark energy coupled with dark matter onto a static Schwarzschild black hole of [Formula: see text] dimensions. Besides the accretion of fluids, the effect due to evaporation of black hole of [Formula: see text] dimensions is under consideration. Mass is one of the interesting dynamical properties of a black hole. The changes in masses have been projected in the framework of the Friedmann–Robertson–Walker model of the universe of [Formula: see text] dimensions. The [Formula: see text]-type Pilgrim dark energies with their logarithmic and power-law entropy corrections are considered as the form of dark energy in our study. Further, the scale factor that is considered as [Formula: see text], [Formula: see text] follows the power-law form. The changes in the dynamical mass of the black hole have been calculated with the variation corresponding to redshift [Formula: see text] while dark matter and specified type of dark energy accrete onto [Formula: see text]-dimensional Schwarzschild black hole. It is found that the dynamical mass of the black hole increases in the late-time epoch as a consequence of the prescribed form of dark energy accretion and evaporation of the black hole. Finally, we discuss the accretion phenomena of the above-specified types of dark energies onto [Formula: see text]-dimensional Morris–Thorne wormhole. It has been investigated that the masses of the black hole and the wormhole sensitively vary with the values of the dimensions.
