The Nucleosynthetic Yields of Core-Collapse Supernovae, prospects for the Next Generation of Gamma-Ray Astronomy
Sydney Andrews, Chris L. Fryer, Samuel W. Jones +2
Though the neutrino-driven convection model for the core-collapse explosion mechanism has received strong support in recent years, there are still many uncertainties in the explosi…
The Impact of Nuclear Physics Uncertainties on Galactic Chemical Evolution Predictions
Benoit Côté, Pavel Denissenkov, Falk Herwig +7
Modeling the evolution of the elements in the Milky Way is a multidisciplinary and challenging task. In addition to simulating the 13 billion years evolution of our Galaxy, chemica…
A direct measurement of the 17O(a,g)21Ne reaction in inverse kinematics and its impact on heavy element production
M. P. Taggart, C. Akers, A. M. Laird +33
During the slow neutron capture process in massive stars, reactions on light elements can both produce and absorb neutrons thereby influencing the final heavy element abundances. A…
The s process in rotating low-mass AGB stars. Nucleosynthesis calculations in models matching asteroseismic constraints
J. W. den Hartogh, R. Hirschi, M. Lugaro +5
Aims. We investigate the s-process during the AGB phase of stellar models whose cores are enforced to rotate at rates consistent with asteroseismology observations of their progeni…
Using failed supernovae to constrain the Galactic r-process element production
B. Wehmeyer, C. Frohlich, B. Côté +2
Rapid neutron capture process (r-process) elements have been detected in a large fraction of metal-poor halo stars, with abundances relative to iron (Fe) that vary by over two orde…
Enrichment of the Galactic disc with neutron-capture elements: Mo and Ru
Tamara Mishenina, Marco Pignatari, Tatiana Gorbaneva +4
We present new observational data for the heavy elements molybdenum (Mo, Z = 42) and ruthenium (Ru, Z = 44) in F-, G-, and K-stars belonging to different substructures of the Milky…
Chromium Nucleosynthesis and Silicon-Carbon Shell Mergers in Massive Stars
Benoit Côté, Samuel Jones, Falk Herwig +1
We analyze the production of the element Cr in galactic chemical evolution (GCE) models using the NuGrid nucleosynthesis yields set. We show that the unusually large [Cr/Fe] abunda…
NuGrid stellar data set - III. Updated low-mass AGB models and s-process nucleosynthesis with metallicities Z=0.01, Z=0.02 and Z=0.03
Umberto Battino, Ashley Tattersall, Claudia Lederer-Woods +6
The production of the neutron-capture isotopes beyond iron that we observe today in the solar system is the result of the combined contribution of the r-process, the s- process and…
Galactic Chemical Evolution of Radioactive Isotopes
Benoit Côté, Maria Lugaro, Rene Reifarth +4
The presence of short-lived (\,Myr) radioactive isotopes in meteoritic inclusions at the time of their formation represents a unique opportunity to study the circumstances th…
Catching Element Formation In The Act
Chris L. Fryer, Frank Timmes, Aimee L. Hungerford +216
Gamma-ray astronomy explores the most energetic photons in nature to address some of the most pressing puzzles in contemporary astrophysics. It encompasses a wide range of objects…
Nucleosynthetic Yields from Neutron Stars Accreting in Binary Common Envelopes
James D. Keegans, Chris L. Fryer, Samuel W. Jones +6
Massive-star binaries can undergo a phase where one of the two stars expands during its advanced evolutionary stage as a giant and envelops its companion, ejecting the hydrogen env…
Enrichment of the Galactic disc with neutron capture elements: Sr
T. Mishenina, M. Pignatari, T. Gorbaneva +4
The enrichment history of heavy neutron-capture elements in the Milky Way disc provides fundamental information about the chemical evolution of our Galaxy and about the stellar sou…
Remnants and ejecta of thermonuclear electron-capture supernovae: Constraining oxygen-neon deflagrations in high-density white dwarfs
S. Jones, F. K. Roepke, C. Fryer +7
(Abridged) The explosion mechanism of electron-capture supernovae (ECSNe) remains equivocal. We attempt to constrain the explosion mechanism (neutron-star-forming implosion or ther…
