Abstract
Using an extended version of quantum hadrodynamics, I propose a new microscopic equation of state (EoS) that is able to correctly reproduce the main properties of symmetric nuclear matter at the saturation density, as well as produce massive neutron stars and satisfactory results for the radius and the tidal parameter. I show that this EoS can reproduce at least a 2.00 solar mass neutron star, even when hyperons are present. The constraints about the radius of a 2.00 M ⊙ and the minimum mass that enables a direct Urca effect are also checked.
