3D hydrodynamical simulations of common-envelope evolution with a 12 solar mass red supergiant donor

These videos are associated with the publication Common envelopes in massive stars: Towards the role of radiation pressure and recombination energy in ejecting red supergiant envelopes (Lau et al. 2022a).


For each simulation, we show the density cross section in the equatorial/orbital plane, in the meridional plane, and in a meridional plane instantaneously co-rotating with the stellar cores.
