This work was supported by the CNRS "Programme National de Physique Stellaire" (PNPS). The numerical simulations were produced on the CEA machine Alfven (founded by DIM ACAV+) and using HPC resources from GENCI-CINES (Grants 2018-047247, and A0080407247). The visualisation of RAMSES data has been done with the OSYRIS python package.
