Popis:	In this work we model compact stars with an equation of state of dark matter with admixed matter. Physical features of an exact solution of the Einstein system are explored by incorporating the effects of linear and nonlinear terms in the equation of state. We present the upper and lower bound masses for our model, and perform a graphical analysis of certain matter variables. We show the influence of the nonlinear term in the equation of state on physical proprieties of the matter distribution within the compact object. In particular the maximum stellar mass of PSRJ0030+0451 is found for the admixed matter distribution.
