摘 要:In the present work,we used five different versions of the quark-meson coupling(QMC)model to compute astrophysical quantities related to the GW170817 event and the neutron star cooling *** of the models are based on the original bag potential structure and three versions consider a harmonic oscillator potential to confine *** bag-like models also incorporate the pasta phase used to describe the inner crust of neutron *** a simple method studied in the present work,we show that the pasta phase does not play a significant ***,the QMC model that satisfies the GW170817 constraints with the lowest slope of the symmetry energy exhibits a cooling profile compatible with observational data.
