Constructing stable 3D hydrodynamical models of giant stars
Sebastian T. Ohlmann, Friedrich K. Roepke, Rüdiger Pakmor +1
Hydrodynamical simulations of stellar interactions require stable models of stars as initial conditions. Such initial models, however, are difficult to construct for giant stars be…
Neutrinos from type Ia supernovae: The gravitationally confined detonation scenario
Warren P. Wright, James P. Kneller, Sebastian T. Ohlmann +3
Despite their use as cosmological distance indicators and their importance in the chemical evolution of galaxies, the unequivocal identification of the progenitor systems and explo…
Magnetic Field Amplification During the Common Envelope Phase
Sebastian T. Ohlmann, Friedrich K. Roepke, Ruediger Pakmor +2
During the common envelope (CE) phase, a giant star in a binary system overflows its Roche lobe and unstable mass transfer leads to a spiral-in of the companion, resulting in a clo…
Three-dimensional simulations of gravitationally confined detonations compared to observations of SN 1991T
Ivo R. Seitenzahl, Markus Kromer, Sebastian T. Ohlmann +9
The gravitationally confined detonation (GCD) model has been proposed as a possible explosion mechanism for Type Ia supernovae in the single-degenerate evolution channel. Driven by…
