NLTE spectral modelling for a carbon-oxygen and helium white-dwarf merger as a Ca-rich transient candidate
F. P. Callan, A. Holas, J. Morán-Fraile +7
We carry out NLTE (non local thermodynamic equilibrium) radiative transfer simulations to determine whether explosion during the merger of a carbon-oxygen (CO) white dwarf (WD) wit…
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…
