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.

Tolman IV type potential
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.
