Left: temperature profiles for a subcritical shock with piston velocity v = 6 km s^-1, at time t = 3.8 × 10⁴ s. Right: temperature profiles for a supercritical shock with piston velocity v = 20 km s^-1, at time t = 7.5 × 10³ s. In both cases, the temperatures are displayed as a function of z = x − vt. The squares represent the gas temperature and the diamonds the radiative temperature. The red curves represent the gas and radiative temperatures obtained with a calculation using 2048 cells, which we take as the “exact” solution. The AMR levels (blue line – right axis) are overplotted.
