Resumen:
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 matter) may exist in the cores of neutron stars as massive as around 2.1M . According to our study, the implications for the recently discovered, massive neutron star PSR J1614?2230, whose gravitational mass is 1.97 ± 0.04M , are that this neutron star may contain an extended region of quark-hybrid matter at it center, but no pure quark matter.
