The compact objects are obtained by solving the Einstein-Maxwell system of equations assuming spherical symmetry in a static spacetime. The spacetime is split in two regions by a spherical surface of coordinate radius $a$. The interior region contains a nonisotropic charged fluid with a de Sitter type equation of state, $p_r = -\\rho_m$, $p_r$ and $\\rho_m$ being respectively the radial pressure and the energy densit","authors_text":"Angel D.
