Weakened inspirals -- I: High mass ratio common envelope interactions in RGB stars
Jack Patrick Nibbs, Orsola De Marco, Lionel Siess +2
The common envelope (CE) interaction between an expanding giant star and a compact companion typically leads to a rapid orbital decay, ending in either a merger or the formation of…

Common envelopes in massive stars III. The obstructive role of radiation transport in envelope ejection
Mike Y. M. Lau, Ryosuke Hirai, Daniel J. Price +2
We present 3D radiation hydrodynamics simulations of common-envelope (CE) evolution involving a 12 solar mass red supergiant donor and a 3 solar mass companion. Existing 3D simulat…
