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…
Thermal-timescale accretion does not always yield critical rotation in mass gainers
Chen Wang, Mike Y. M. Lau, Xiang-Dong Li +7
Binary evolution plays a central role in producing rapidly rotating stars. Previous studies have shown that mass gainers in binaries can reach critical rotation after accreting onl…
1D stellar mergers: entropy sorting and PyMMAMS
Max Heller, Fabian R. N. Schneider, Jan Henneco +2
Stellar multiple systems are the norm, not the exception, with many systems undergoing interaction phases during their lifetimes. A subset of these interactions can lead to stellar…
Magnetically driven outflows in 3D common-envelope evolution of massive stars
Marco Vetter, Friedrich K. Roepke, Fabian R. N. Schneider +7
Recent three-dimensional magnetohydrodynamical simulations of the common-envelope interaction revealed the self-consistent formation of bipolar magnetically driven outflows launche…
Stellar mergers and common-envelope evolution
Fabian R. N. Schneider, Mike Y. M. Lau, Friedrich K. Roepke
Stellar mergers and common-envelope evolution are fast (dynamical-timescale) interactions in binary stars that drastically alter their evolution. They are key to understanding a pl…
From spherical stars to disk-like structures: 3D common-envelope evolution of massive binaries beyond inspiral
M. Vetter, F. K. Roepke, F. R. N. Schneider +4
Three-dimensional simulations usually fail to cover the entire dynamical common-envelope phase of gravitational wave progenitor systems due to the vast range of spatial and tempora…
