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.
