... system

In fact the total energy is slightly modified, due to the particle mass and density changes which imply a change in the total potential. However, this change is very small compared to the total potential of the cluster and may be neglected.

At these temperatures and densities, the cooling is so strong that it dominates the adiabatic compression heating.

As the cold gas production of model 4 is nearly two decades below the observations, we haven't displayed it.
