Long time Overturn Study in the second phase of the moon cooling using numerical and perturbated Boussinesq equations

We simulated the unstable convection processes unearthed by L.Collin in the second phase of the moon cooling using Dedalus. We unearthed a slow settling of the overturning circulation contradicting previous assumptions in the litterature and we justified that by a perturbation analysis of the governing equations. We also studied the consequences of the thermal profiles and the Raleigh in the strength of the overturning circulation.
