Energy Release Associated with Quark Phase Transition in Neutron Stars:   Comparative Analysis of Maxwell and Glendenning Scenarios
  We study the compact stars internal structure and observable characteristics alterations due to the quark deconfinement phase transition. To proceed with, we investigate the properties of isospin-asymmetric nuclear matter in the improved relativistic mean-field (RMF) theory, including a scalar-isovector \delta-meson effective field. In order to describe the quark phase, we use the improved version of the MIT bag model, in which the interactions between u, d and s quarks inside the bag are taken into account in the one-gluon exchange approximation. We compute the amount of energy released by the corequake for both cases of deconfinement phase transition scenarios, corresponding to the Maxwellian type ordinary first-order phase transition and the phase transition with formation of a mixed quark-hadron phase (Glendenning scenario).
