Anisotropic Charged Solutions for Quark Stars with Linear Equation of State

We present two new classes of solutions for the Einstein-Maxwell system of field equations in a spherically symmetric spacetime considering the MIT bag model equation of state and a particular form of one of the metric potentials. The obtained solutions can be written in terms of elementary functions, namely polynomials and algebraic functions. The first class has a singularity at the centre. For the second class a physical analysis indicates that is regular and well behaved in the stellar interior.
