Constraints on explosive silicon burning in core-collapse supernovae from measured Ni/Fe ratios
A. Jerkstrand, F. X. Timmes, G. Magkotsios +7
Measurements of explosive nucleosynthesis yields in core-collapse supernovae provide tests for explosion models. We investigate constraints on explosive conditions derivable from m…
The light curve of SN 1987A revisited: constraining production masses of radioactive nuclides
I. R. Seitenzahl, F. X. Timmes, G. Magkotsios
We revisit the evidence for the contribution of the long-lived radioactive nuclides 44Ti, 55Fe, 56Co, 57Co, and 60Co to the UVOIR light curve of SN 1987A. We show that the V-band l…
Freeze-out yields of radioactivities in core-collapse supernovae
Georgios Magkotsios, F. X. Timmes, Michael Wiescher
We explore the nucleosynthesis trends from two mechanisms during freeze-out expansions in core-collapse supernovae. The first mechanism is related to the convection and instabiliti…
Trends in Ti44 and Ni56 from Core-Collapse Supernovae
Georgios Magkotsios, Francis X. Timmes, Aimee L. Hungerford +3
We compare the yields of Ti44 and Ni56 produced from post-processing the thermodynamic trajectories from three different core-collapse models -- a Cassiopeia A progenitor, a double…
The effect of 12C + 12C rate uncertainties on s-process yields
M E Bennett, R Hirschi, M Pignatari +9
The slow neutron capture process in massive stars (the weak s-process) produces most of the s-only isotopes in the mass region 60 < A < 90. The nuclear reaction rates used in simul…
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…
