The vector MIT bag model under the light of new data

Maíra Cesário Alvim Lobo · Débora Peres Menezes

In the present work we use the vector MIT bag model to describe quark matter and obtain the macroscopic properties of neutron stars. We also calculate the speed of sound of quark matter described by this model with specific parameter values and check if the results obey the conformal limit at high densities. We have seen that the vector MIT bag model produces stars with masses and radii consistent with recent data, suggesting the possible existence of massive quark (or strange) stars.
