Radial 1D-averaged profiles for M1 simulation. Left: thermal and kinetic specific energy profiles. Right: density and temperature profiles. The dashed magenta vertical line is R_atm as defined in Sect. 2.2. The thermal energy is more than one order of magnitude higher than the kinetic energy, i.e., the atmosphere is pressure supported. Inside R_atm, the kinetic energy is significantly higher than outside. This is because of the azimuthal velocity component: Inside R_atm, the gas rotates around the core.
