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…
Quantitative spectral analysis of the sdB star HD 188112: a helium-core white dwarf progenitor
M. Latour, U. Heber, A. Irrgang +7
HD 188112 is a bright (V = 10.2 mag) hot subdwarf B (sdB) star with a mass too low to ignite core helium burning and is therefore considered as a pre-extremely low mass (ELM) white…
Type Ia supernovae from violent mergers of carbon-oxygen white dwarfs: polarisation signatures
M. Bulla, S. A. Sim, R. Pakmor +5
The violent merger of two carbon-oxygen white dwarfs has been proposed as a viable progenitor for some Type Ia supernovae. However, it has been argued that the strong ejecta asymme…
The interaction of core-collapse supernova ejecta with a companion star
Zheng-Wei Liu, Thomas M. Tauris, Friedrich K. Roepke +4
The progenitors of many CCSNe are expected to be in binary systems. After the SN explosion, the companion may suffer from mass stripping and be shock heated as a result of the impa…
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…
500 Days of SN 2013dy: spectra and photometry from the ultraviolet to the infrared
Y. -C. Pan, R. J. Foley, M. Kromer +23
SN 2013dy is a Type Ia supernova for which we have compiled an extraordinary dataset spanning from 0.1 to ~ 500 days after explosion. We present 10 epochs of ultraviolet (UV) throu…
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…
