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…
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…
Large-scale ordered magnetic fields generated in mergers of helium white dwarfs
Rüdiger Pakmor, Ingrid Pelisoli, Stephen Justham +9
Stellar mergers are one important path to highly magnetised stars. Mergers of two low-mass white dwarfs may create up to every third hot subdwarf star. The merging process is usual…
Faint calcium-rich transient from the double-detonation of a carbon-oxygen white dwarf star
J. Moran-Fraile, A. Holas, F. K. Roepke +2
We have computed a three-dimensional hydrodynamic simulation of the merger between a massive () helium white dwarf (He WD) and a low-mass () carbon-oxyg…
Scalable stellar evolution forecasting: Deep learning emulation vs. hierarchical nearest neighbor interpolation
K. Maltsev, F. R. N. Schneider, F. K. Roepke +5
Many astrophysical applications require efficient yet reliable forecasts of stellar evolution tracks. One example is population synthesis, which generates forward predictions of mo…
Bipolar planetary nebulae from common envelope evolution of binary stars
P. A. Ondratschek, F. K. Roepke, F. R. N. Schneider +5
Asymmetric shapes and evidence for binary central stars suggest a common-envelope origin for many bipolar planetary nebulae. The bipolar components of the nebulae are observed to e…
