Estimating the Role of Bag Constant and Modified Theory on Anisotropic Stellar Models

Tayyab Naseer, M. Sharif

In this article, we are devoted to discuss different compact stars admitting anisotropic interiors in a particular modified theory of gravity. For this purpose, a spherically symme…

Analytical and numerical study of accretion processes around charged spherically symmetric black holes in scalar-tensor Gauss-Bonnet gravity

G. Mustafa, O. Donmez, A. Errehymy +5

We investigate the physical phenomena occurring around a spherically symmetric, non-rotating charged black hole (BH) to explore the effects of scalar-tensor Gauss-Bonnet gravity on…
