Universality and variability of the heavy r-process element abundance pattern from a nonequilibrium approach
David Blaschke, Friedrich K. Röpke, Gerd Röpke
A striking feature in the observed chemical composition of the majority of stars is the universality of the relative abundances of the heavy elements, although some outliers exist.…
Continuous mass ablation of planets engulfed in stellar envelopes
Mike Y. M. Lau, Robert Andrassy, Giovanni Leidi +4
Most stars host short-period planets that are expected to be engulfed during post-main-sequence expansion. The dissolution of engulfed planets has been proposed as a possible mecha…
Phlegethon: a fully compressible magnetohydrodynamic code for simulations in stellar astrophysics
G. Leidi, A. Holas, K. Vitovsky +12
We present PHLEGETHON, a fully compressible, Eulerian magnetohydrodynamic (MHD) code designed for multidimensional simulations in stellar astrophysics. The code uses a time-explici…
Violent mergers revisited: The origin of the fastest stars in the Galaxy
Rüdiger Pakmor, Ken J. Shen, Aakash Bhat +12
Binary systems of two carbon-oxygen white dwarfs are one of the most promising candidates for the progenitor systems of Type Ia supernovae. Violent mergers, where the primary white…
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…
Type Ia supernova explosion models are inherently multidimensional
R. Pakmor, I. R. Seitenzahl, A. J. Ruiter +5
Theoretical and observational approaches to settling the important questions surrounding the progenitor systems and the explosion mechanism of normal Type Ia supernovae have thus f…
The type Iax supernova, SN 2015H: a white dwarf deflagration candidate
M. R. Magee, R. Kotak, S. A. Sim +22
We present results based on observations of SN 2015H which belongs to the small group of objects similar to SN 2002cx, otherwise known as type Iax supernovae. The availability of d…
Light curves for off-centre ignition models of type Ia supernovae
S. A. Sim, D. N. Sauer, F. K. Röpke +1
Motivated by recent models involving off-centre ignition of type Ia supernova explosions, we undertake three-dimensional time-dependent radiation transport simulations to investiga…
