H-He Shell Interactions and Nucleosynthesis in Massive Population III Stars
Ondrea Clarkson, Falk Herwig, Robert Andrassy +3
We report on our ongoing investigation into the nucleosynthetic and hydrodynamic nature of mixing at the interface between the H- and He-convection zones in massive Pop III stars.…
The s process in AGB stars as constrained by a large sample of Barium stars
B. Cseh, M. Lugaro, V. D'Orazi +8
Context. Barium (Ba) stars are dwarf and giant stars enriched in elements heavier than iron produced by the slow neutron-capture process (s process). They belong to binary systems…
The i-process yields of rapidly-accreting white dwarfs from multicycle He-shell flash stellar evolution models with mixing parameterizations from 3D hydrodynamics simulations
Pavel Denissenkov, Falk Herwig, Paul Woodward +3
We have modelled the multicycle evolution of rapidly-accreting CO white dwarfs (RAWDs) with stable H burning intermittent with strong He-shell flashes on their surfaces for $0.7\le…
Neutron Star Mergers Might not be the Only Source of r-Process Elements in the Milky Way
Benoit Côté, Marius Eichler, Almudena Arcones +8
Probing the origin of r-process elements in the universe represents a multi-disciplinary challenge. We review the observational evidence that probe the properties of r-process site…
i-Process Contribution of Rapidly Accreting White Dwarfs to the Solar Composition of First-Peak Neutron-Capture Elements
Benoit Côté, Pavel Denissenkov, Falk Herwig +4
Rapidly accreting white dwarfs (RAWDs) have been proposed as contributors to the chemical evolution of heavy elements in the Galaxy. Here, we test this scenario for the first time…
Role of core-collapse supernovae in explaining Solar System abundances of p nuclides
C. Travaglio, T. Rauscher, A. Heger +2
The production of the heavy stable proton-rich isotopes between 74Se and 196Hg -- the p nuclides -- is due to the contribution from different nucleosynthesis processes, activated i…
