We perform a careful investigation of the problem of physically realistic gravitational collapse
of massive stars in f (R) gravity. We show that the extra matching conditions that arise in the …

We obtain a class of regular black hole solutions in four-dimensional f (R) gravity, R being
the curvature scalar, coupled to a nonlinear electromagnetic source. The metric formalism is …

Solving field equations in the context of higher curvature gravity theories is a formidable
task. However, in many situations, eg, in the context of f (R) theories, the higher curvature …

We study the instabilities and related anti-evaporation of the extremal Reissner–Nordström
(RN) black hole in F (R) gravity. It is remarkable that the effective electric charge can be …

The null geodesics of the regular and rotating magnetically charged black hole in a non-
minimally coupled Einstein-Yang-Mills theory surrounded by a plasma medium is studied …

We find exact nonstatic null-dust solutions in metric f (R) gravity, imposed by the constant
scalar curvature, which describes the gravitational collapse of null dust in (anti-) de Sitter [(A) …

We generalize the Buchdahl–Bondi limit for the case of static, spherically symmetric,
relativistic compact stars immersed in Schwarzschild vacuum in the f (R)-theory of gravity …

We investigate the future evolution of the Nariai black hole, which is the extremal limit of the
Schwarzschild–de Sitter one in modified gravity. The perturbation equations around the …

In this paper, we study charged wormhole solutions in f (T) gravity with non-commutative
background. We develop field equations using effective energy-momentum tensor for …

In this paper, we study the Power-Law Entropy-Corrected Holographic Dark Energy
(PLECHDE) model in the framework of Hořava-Lifshitz cosmology considering a non-flat …
