    Stability of Quark Star Model
    (Communications in Theoretical Physics, IOP Sciences, 2016-03-01) Mardan Azmi, Syed Ali; Rehman, Muhammad Aziz
    In this paper, we investigate the stability of quark stars with four different types of inner matter configurations; isotropic, charged isotropic, anisotropic and charged anisotropic by using the concept of cracking. For this purpose, we have applied local density perturbations technique to the hydrostatic equilibrium equation as well as on physical parameters involved in the model. We conclude that quark stars become potentially unstable when inner matter configuration is changed and electromagnetic field is applied.
