Tematy:: Einstein-Maxwell system
MIT bag model EOS
exact solutions
Opis:: Two classes of exact solutions to the Einstein-Maxwell system is found in terms of elementary function. This is achieved by choosing a particular form for the measure of anisotropy with the MIT bag model equation of state relating the radial pressure to the energy density consistent with quark stars. These solutions contain the models found previously in the limit of vanishing charge/measure of anisotropy. Isotropic exact solutions regained include models by Komathiraj and Maharaj; Mak and Harko; and Misner and Zapolsky. A physical analysis of the matter and electromagnetic variables indicates that the model is well behaved and regular.

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 particular form for the measure of anisotropy and a metric function which depends on an adjustable parameter α. Variables as the energy density, charge density, radial pressure and the metric functions are written in terms of elementary and polynomial functions. We show that the form chosen for the metric function allows obtain physically acceptable solutions with any value of the adjustable parameter.

Tytuł:: Quark star model with Tolman VII Type Potential
Autorzy:: Malaver, Manuel
Powiązania:: https://bibliotekanauki.pl/articles/1192872.pdf
Data publikacji:: 2016
Wydawca:: Przedsiębiorstwo Wydawnictw Naukowych Darwin / Scientific Publishing House DARWIN
Tematy:: Relativistic objects
anisotropic factor
MIT–Bag model
Tolman VII type potential
Charge density
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

metric function
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.
