<h2>3D hydrodynamical simulations of common-envelope evolution with a 12 solar mass red supergiant donor</h2>
<p>These videos are associated with the publication <i>Common envelopes in massive stars: Towards the role of radiation pressure and recombination energy in ejecting red supergiant envelopes</i> <a href="https://ui.adsabs.harvard.edu/abs/2022MNRAS.512.5462L/abstract">(Lau et al. 2022a)</a>.</p>
<br>
<p>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.</p>
