Abstract: In this paper, we have studied the stability of neutron stars in the background of Palatini f(R, T) gravity. In this context, the static spherically symmetric geometry is considered which is assumed to be coupled… read more here.

Abstract: We explore equilibrium solutions of spherically symmetric boson stars in the Palatini formulation of f(R) gravity. We account for the modifications introduced in the gravitational sector by using a recently established correspondence between modified gravity… read more here.

DOI: 10.1103/physrevd.102.104012
Abstract: We study the structure and stability of traversable wormholes built as (spherically symmetric) thin shells in the context of Palatini f(R) gravity. Using a suitable junction formalism for these theories we find that the effective… read more here.

DOI: 10.1103/physrevd.99.064053
Abstract: We consider the space-time metric generated by a global monopole in an extension of General Relativity (GR) of the form $f(\mathcal{R})=\mathcal{R}-\lambda \mathcal{R}^2$. The theory is formulated in the metric-affine (or Palatini) formalism and exact analytical… read more here.
