r-Process nucleosynthesis from hyperaccreting neutron stars in common envelopes
Peter Anninos, Matthew Portman, Scott Carmichael +2
We investigate nuclear reactions and feedback in hyperaccreting neutron star environments, considering accretion rates in the range 0.3 - yr, typical…
The Occurrence and Impact of Carbon-Oxygen Shell Mergers in Massive Stars
L. Roberti, M. Pignatari, H. E. Brinkman +6
In their final stages before undergoing a core-collapse supernova, massive stars may experience mergers between internal shells where carbon (C) and oxygen (O) are consumed as fuel…
Production of 44Ti and iron-group nuclei in the ejecta of 3D neutrino-driven supernovae
Andre Sieverding, Daniel Kresse, Hans-Thomas Janka
The radioactive isotopes of 44Ti and 56Ni are important products of explosive nucleosynthesis, which play a key role for supernova (SN) diagnostics and were detected in several nea…
The -process nucleosynthesis in core-collapse supernovae. I. A novel analysis of -process yields in massive stars
L. Roberti, M. Pignatari, A. Psaltis +4
The -process nucleosynthesis in core-collapse supernovae is generally accepted as a feasible process for the synthesis of neutron-deficient isotopes beyond iron. However, crucia…
Production of -nuclei from -process seeds: the -process
Zewei Xiong, Gabriel Martínez-Pinedo, Oliver Just +1
We present a new nucleosynthesis process that may take place on neutron-rich ejecta experiencing an intensive neutrino flux. The nucleosynthesis proceeds similarly to the standard…
Tracer particles for core-collapse supernova nucleosynthesis: The advantages of moving backward
Andre Sieverding, Preston G. Waldrop, J. Austin Harris +4
After decades, the theoretical study of core-collapse supernova explosions is moving from parameterized, spherically symmetric models to increasingly realistic multi-dimensional si…
