Tolman VII type potential
Opis:: In this paper, we study the behaviour of compact relativistic objects with charged anisotropic matter distribution considering Tolman VII type potential for the gravitational potential Z(x) and a particular form of the metric function y(x) proposed for Komathiraj and Maharaj (2007). The Einstein-Maxwell field equations are integrated analytical and we obtain the radial pressure, energy density, charge density, anisotropy and the mass function. A physical analysis of electromagnetic field indicates that is regular at the origin and well behaved. The new stellar model satisfies all physical properties in a realistic star.

Tematy:: Adjustable parameter

Gravitational potential
Relativistic objects
Opis:: In this paper, we studied the behavior of relativistic objects with anisotropic charged matter distribution considering a prescribed form for the gravitational potential Z(x) which depends on an adjustable parameter n. The equation of state presents a quadratic relation between the energy density and the radial pressure. New exact solutions of the Einstein-Maxwell system are generated. A physical analysis of electromagnetic field indicates that is regular in the origin and well behaved. We show as a variation of the adjustable parameter n causes a modification in the charge density, the radial pressure and the mass of the stellar object.

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.

Tematy:: Charged anisotropic matter

lineal equation of state
Opis:: In this paper, we studied the behavior of relativistic objects considering Tolman IV form for the gravitational potential Z and a lineal equation of state within the framework of MIT-Bag model for the charged anisotropic matter. A physical analysis of electromagnetic field indicates that is regular in the origin and well behaved. The new obtained solution not admits singularities in the matter, charge density and metric functions. A graphical analysis indicates that the new stellar model satisfy all physical properties expected in a realistic star.

Opis:: In this paper, we study the behaviour of compact relativistic objects with charged anisotropic matter distribution considering modified Tolman IV type potential for the gravitational potential Z(x) which depends on an adjustable parameter α and a particular form of the metric function y(x) used by Malaver (2009). The Einstein-Maxwell fields equations are integrated analytical and we obtain the radial pressure, energy density, charge density, anisotropy and the mass function. A physical analysis of electromagnetic field indicates that is regular at the origin and well behaved. The new stellar models satisfies all physical properties in a realistic star for any value of the adjustable parameter.
