A Comparison of Grid-Based and SPH Binary Mass-Transfer and Merger Simulations
Patrick M Motl, Juhan Frank, Jan Staff +5
Currently there is great interest in the outcomes and astrophysical implications of mergers of double degenerate binaries. In a commonly adopted approximation, the components of su…
NuGrid stellar data set I. Stellar yields from H to Bi for stars with metallicities Z = 0.02 and Z = 0.01
M. Pignatari, F. Herwig, R. Hirschi +16
We provide a set of stellar evolution and nucleosynthesis calculations that applies established physics assumptions simultaneously to low- and intermediate-mass and massive star mo…
Generating Optimal Initial Conditions for Smoothed Particle Hydrodynamics Simulations
Steven Diehl, Gabriel Rockefeller, Christopher L. Fryer +2
We review existing SPH setup methods and outline their advantages, limitations and drawbacks. We present a new method for constructing initial conditions for smoothed particle hydr…
The effect of 12C + 12C rate uncertainties on the evolution and nucleosynthesis of massive stars
M. E. Bennett, R. Hirschi, M. Pignatari +8
[Shortened] The 12C + 12C fusion reaction has been the subject of considerable experimental efforts to constrain uncertainties at temperatures relevant for stellar nucleosynthesis.…
Simulating the Common Envelope Phase of a Red Giant Using SPH and Uniform Grid Codes
Jean-Claude Passy, Orsola De Marco, Chris L. Fryer +6
We use three-dimensional hydrodynamical simulations to study the rapid infall phase of the common envelope interaction of a red giant branch star of mass equal to 0.88 \msun and a…
The effect of 12C + 12C rate uncertainties on the weak s-process component
Michael E. Bennett, Raphael Hirschi, Marco Pignatari +9
The contribution by massive stars (M > 9 solar masses) to the weak s-process component of the solar system abundances is primarily due to the 22Ne neutron source, which is activate…
