Hydrodynamic moving-mesh simulations of the common envelope phase in binary stellar systems
Sebastian T. Ohlmann, Friedrich K. Roepke, Ruediger Pakmor +1
The common envelope (CE) phase is an important stage in binary stellar evolution. It is needed to explain many close binary stellar systems, such as cataclysmic variables, Type Ia…
Neutrino and gravitational wave signal of a delayed-detonation model of Type Ia supernovae
Ivo R. Seitenzahl, Matthias Herzog, Ashley J. Ruiter +3
The progenitor system(s) and the explosion mechanism(s) of Type Ia supernovae (SNe Ia) are still under debate. Non-electromagnetic observables, in particular gravitational waves an…
Type Ia supernovae from exploding oxygen-neon white dwarfs
Kai S. Marquardt, Stuart A. Sim, Ashley J. Ruiter +5
The progenitor problem of Type Ia supernovae (SNe Ia) is still unsolved. Most of these events are thought to be explosions of carbon-oxygen (CO) white dwarfs (WDs), but for many of…
Deflagrations in hybrid CONe white dwarfs: a route to explain the faint Type Iax supernova 2008ha
M. Kromer, S. T. Ohlmann, R. Pakmor +7
Stellar evolution models predict the existence of hybrid white dwarfs (WDs) with a carbon-oxygen core surrounded by an oxygen-neon mantle. Being born with masses ~1.1 Msun, hybrid…
Improving the convergence properties of the moving-mesh code AREPO
Ruediger Pakmor, Volker Springel, Andreas Bauer +5
Accurate numerical solutions of the equations of hydrodynamics play an ever more important role in many fields of astrophysics. In this work, we reinvestigate the accuracy of the m…
The origin of the cosmic gamma-ray background in the MeV range
Pilar Ruiz-Lapuente, Lih-Sin The, Dieter Hartmann +5
There has been much debate about the origin of the diffuse --ray background in the MeV range. At lower energies, AGNs and Seyfert galaxies can explain the background, but not ab…
