Left: temporal evolution of the shock radius (solid) and of the PNS radius (dashed) for each of the four spherically symmetric CCSN models. Models differ by the nuclear EOSs, including two versions of the BLh EOS and two RMF EOSs, namely HS(TM1) and SFHo. The two BLh EOSs use the HS(TM1) and the SFHo EOS for the low-density regime (n <  n_th). We note the logarithmic scale on the time axis. Right: same as on the left panel, but for the central density (solid) and temperature (dashed). The cyan (blue) shaded area represents matter below (above) the threshold density n_th (used to join the BLh and the HS(TM1) EOS) for the BLh+TM1 model.
