We investigate the gravitational models with the non-minimal $$Y(R)F^2$$Y(R)F2 coupled electromagnetic fields to gravity, in order to describe charged compact stars, where Y(R) denotes a function of the Ricci curvature scalar R and $$F^2$$F2 denotes the Maxwell invariant term. We determine two parameter family of exact spherically symmetric static solutions and the corresponding non-minimal model without assuming any relation between energy density of matter and pressure. We give the mass…

In this paper we investigate the gravitational vacuum stars which called gravastars in the non-minimally coupled models with electromagnetic and gravitational fields. We consider two non-minimal

Anisotropic Stars in the Non-minimal Y ( R ) F 2 Gravity

We investigate anisotropic compact stars in the non-minimal Y (R)F 2 model of gravity which couples an arbitrary function of curvature scalar Y (R) to the electromagnetic field invariant F 2. After

Effect of vacuum polarization on the magnetic fields around a Schwarzschild black hole

It is a well known result that the effect of vacuum polarization in gravitational fields will lead to a non-minimal coupling between gravity and electromagnetism. We investigate this phenomenon

Anisotropic inflation with a non-minimally coupled electromagnetic field to gravity

We consider the non-minimal model of gravity in Y(R) F2-form. We investigate a particular case of the model, for which the higher order derivatives are eliminated but the scalar curvature R is kept

We study the effect of electric charge in compact stars assuming that the charge distribution is proportional to the mass density. The pressure and the density of the matter inside the stars are

With the question, "Can relativistic charged spheres form extremal black holes?" in mind, we investigate the properties of such spheres from a classical point of view. The investigation is carried
