A stellar model with an electrically charged anisotropic fluid as a source of matter is
presented. The radial pressure is described by a Chaplygin state equation, P r (ρ)= μ c 2 ρ …

In this paper, a significant leap forward in understanding compact stellar systems and the
modified f (Q) gravity theory is achieved. The pivotal discovery lies in the successful …

The astronomical observations on the accelerated expansion of the universe generate the
possibility that the internal matter of the stars is not only formed by ordinary matter but also …

Abstract For the Einstein-Maxwell equation system, with perfect fluid in a static and
spherically symmetrical spacetime, we report an analytical internal solution which is …

In this paper, we present a new exact anisotropic charged version of Pant's interior solution
[Astrophys. Space Sci. 331, 633 (2011)] by employing the embedding class I condition and …

Starting from a perfect fluid solution we constructed a generalization with anisotropic
pressures and regular geometry as well as the pressures, the density and the speed of …

A simple geometry which is static and spherically symmetrical is proposed, useful to model a
fluid sphere in general relativity. This allows us to describe the interior of stellar objects both …

In the description of neutron stars, it is very important to consider gravitational theories as
general relativity, due to the determining influence on the behavior of the different types of …

In this investigation report, we present a perfect charged fluid solution for a static and
spherically symmetric spacetime; for its construction, we suppose a metric potential, gtt, and …

In this paper, we analyse an analytical solution of the Einstein–Maxwell field equations that
considers matter with anisotropic pressures in a static and spherically symmetric geometry …
