Abstract

We study the dynamics of massive particles around the non-Schwarzschild black hole. The effective potential, energy, and angular momentum are investigated using the Lagrangian formalism. In addition, we explore the energy extraction from the weakly charged non-Schwarzschild black hole through the electric Penrose process. The radiation of the accretion disk is also analyzed using the Novikov-Thorne model for the accretion disk. It was found that the values of the important quantities, including the flux of electromagnetic radiation, the accretion disk’s temperature, differential and spectral luminosities, increase with the rise of the spacetime deformation parameter.
