Opis:: In this paper, we studied the behavior of relativistic objects with charged anisotropic matter distribution within the framework of MIT-Bag Model considering Tolman VII form for the gravitational potential Z. A physical analysis of electromagnetic field indicates that is regular in the origin and well behaved. In the obtained solution there is a singularity in the charge density. We show as the presence of an electrical field causes a modification in the radial pressure, the tangential pressure, the anisotropic factor and the mass of the stellar object.

Opis:: We found new class of solutions to the Einstein-Maxwell system of equations for charged quark matter within the framework of MIT Bag Model considering a prescribed form of gravitational potential Z(x) used by Malaver (2016), which depends on an adjustable parameter n. Variables as the energy density, charge density, pressure and the metric functions are written in terms of elementary and polynomial functions. We show that the form chosen for the gravitational potential allows obtain physically acceptable solutions with any value of the adjustable parameter.

Tytuł:: Analytical models for compact stars with a linear equation of state
Autorzy:: Malaver, Manuel
Powiązania:: https://bibliotekanauki.pl/articles/1191971.pdf

Tematy:: Einstein-Maxwell system

exact solution
Opis:: In this paper, we found two new classes of solutions to the Einstein-Maxwell system of equations for compact stars assuming an anisotropic pressure and a linear equation of state for the matter distribution within the framework of MIT-Bag Model with a particular form of the metric function. The exact solutions can be written in terms of elementary function in presence of an electromagnetic field. All the obtained models have a singularity in the charge density but not admit singularities in the matter and metric functions at the centre.
