Dynamical friction in stratified stellar envelopes
Damien Gagnier
Dynamical friction prescriptions used for common-envelope and planetary engulfment inspirals often assume a homogeneous medium and/or rectilinear perturber motion. A gravitating ob…
Continuous mass ablation of planets engulfed in stellar envelopes
Mike Y. M. Lau, Robert Andrassy, Giovanni Leidi +4
Most stars host short-period planets that are expected to be engulfed during post-main-sequence expansion. The dissolution of engulfed planets has been proposed as a possible mecha…
Phlegethon: a fully compressible magnetohydrodynamic code for simulations in stellar astrophysics
G. Leidi, A. Holas, K. Vitovsky +12
We present PHLEGETHON, a fully compressible, Eulerian magnetohydrodynamic (MHD) code designed for multidimensional simulations in stellar astrophysics. The code uses a time-explici…
Local simulations of common-envelope dynamical inspiral. Impact of rotation, accretion, and stratification
D. Gagnier, G. Leidi, M. Vetter +2
Common envelope evolution (CEE) is a crucial phase in binary stellar evolution. Current global three-dimensional simulations lack the resolution to capture the small-scale dynamics…
