Gravitational mass M of non-rotating NSs versus baryonic mass M_b for the unified Brussels-Montreal EoSs based on the EDFs BSk19-20-21, and for the SLy EoS based on the SLy4 EDF. The filled and empty rectangles indicate the constraints inferred from the assumption that pulsar J0737–3039B was formed in an electron-capture supernova as obtained by Kitaura et al. (2006) and by Podsiadlowski et al. (2005), respectively.
