Comparison of the EOS at β-equilibrium for zero temperature (T = 0) and for a constant entropy per particle of s = 0.5 k_B for DD2F-RDF-1.1 (solid light and dark blue lines) and DD2F (dashed red and magenta lines) with the corresponding DD2F hadronic EOS (red and magenta dashed lines, respectively, which are on top of each other for both configurations). Left panel: pressure P versus rest-mass density ρ. Right panel: mass M radius R relation. Included is an example for the high-precision maximum mass constraint of 2.01 ± 0.04 M_⊙ (light grey band) deduced from the radio observations of PSR J0348+0432 of Antoniadis et al. (2013). The horizontal grey line in the mass-radius diagram marks the onset mass for the quark-hadron phase transition at M = 1.582 M_⊙ for the EOS with s = 0.5 k_B.
