First Simulations of Core- Collapse Supernovae to Supernova Remnants with SNSPH
Carola I. Ellinger, Gabriel Rockefeller, Christopher L. Fryer +2
We present the first 3-dimensional simulations following the evolution of supernova shocks from their inception in the stellar core through the development of a supernova remnant i…
The 12C + 12C reaction and the impact on nucleosynthesis in massive stars
M. Pignatari, R. Hirschi, M. Wiescher +7
Despite much effort in the past decades, the C-burning reaction rate is uncertain by several orders of magnitude, and the relative strength between the different channels 12C(12C,a…
A Case Study of Small Scale Structure Formation in 3D Supernova Simulations
Carola I. Ellinger, Patrick A. Young, Christopher L. Fryer +1
It is suggested in observations of supernova remnants that a number of large- and small-scale structures form at various points in the explosion. Multidimensional modeling of core-…
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…
56Ni Production in Double Degenerate White Dwarf Collisions
Cody Raskin, Evan Scannapieco, Gabriel Rockefeller +3
We present a comprehensive study of white dwarf collisions as an avenue for creating type Ia supernovae. Using a smooth particle hydrodynamics code with a 13-isotope, α-chain nucle…
