Third family of compact stars within a nonlocal chiral quark model equation of state
(American Physical Society, 2019-03)
A class of hybrid compact star equations of state is investigated that joins by a Maxwell construction a low-density phase of hadronic matter, modeled by a relativistic mean-field approach with excluded nucleon volume, ...
Quark-hybrid matter in the cores of massive neutron stars
(American Physical Society, 2013-01)
Using a nonlocal extension of the SU(3) Nambu-Jona-Lasinio model, which reproduces several of the key features of quantum chromodynamics, we show that mixed phases of deconfined quarks and confined hadrons (quark-hybrid ...
Constant entropy hybrid stars: A first approximation of cooling evolution
(EDP Sciences, 2017-05)
Aims. We aim to study the possibility of a hadron-quark phase transition in the interior of neutron stars, taking into account different schematic evolutionary stages at finite temperature. We also discuss the strange quark ...
