Complete nucleosynthesis calculations for low-mass stars from NuGrid

Marco Pignatari, Falk Herwig, Michael Bennett +8

Many nucleosynthesis and mixing processes of low-mass stars as they evolve from the Main Sequence to the thermal-pulse Asymptotic Giant Branch phase (TP-AGB) are well understood (a…

Spatial Distribution of Nucleosynthesis Products in Cassiopeia A: Comparison Between Observations and 3D Explosion Models

Patrick Young, Carola I. Ellinger, Francis X. Timmes +10

We examine observed heavy element abundances in the Cassiopeia A supernova remnant as a constraint on the nature of the Cas A supernova. We compare bulk abundances from 1D and 3D e…

NuGrid: s process in massive stars

Raphael Hirschi, Urs Frischknecht, F. -K. Thielemann +10

The s-process production in massive stars at very low metallicities is expected to be negligible due to the low abundance of the neutron source 22Ne, to primary neutron poisons and…

Nucleosynthesis simulations for a wide range of nuclear production sites from NuGrid

Falk Herwig, Michael Bennett, Steven Diehl +8

Simulations of nucleosynthesis in astrophysical environments are at the intersection of nuclear physics reaction rate research and astrophysical applications, for example in the ar…

44Ti and 56Ni in core-collapse supernovae

Georgios Magkotsios, Francis X. Timmes, Michael Wiescher +9

We investigate the physical conditions where 44Ti and 56Ni are created in core-collapse supernovae. In this preliminary work we use a series of post-processing network calculations…

Nucleosynthetic Yields from "Collapsars"

Gabriel Rockefeller, Christopher L. Fryer, Patrick Young +8

The "collapsar" engine for gamma-ray bursts invokes as its energy source the failure of a normal supernova and the formation of a black hole. Here we present the results of the fir…
