The s-process at Subsolar Metallicity: Insights from High-Resolution Infrared Spectroscopy of Magellanic Cloud Planetary Nebulae
N. C. Sterling, M. G. Stephenson, Harriet L. Dinerstein +8
We present observations of 12 Magellanic Cloud planetary nebulae (PNe) obtained with the high-resolution near-infrared spectrometer IGRINS on Gemini South. In 10 targets we detect…
Slow White Dwarf Mergers as a New Galactic Source of Trans-Iron Elements
Umberto Battino, Claudia Lederer-Woods, Claudia Travaglio +2
The astrophysical origins of the heaviest stable elements that we observe today in the Solar System are still not fully understood. Recent studies have demonstrated that H-accretin…
The NuGrid AGB Evolution and Nucleosynthesis Data Set
Umberto Battino, Marco Pignatari, Ashley Tattersall +2
Asymptotic Giant Branch (AGB) stars play a key role in the chemical evolution of galaxies. These stars are the fundamental stellar site for the production of light elements such as…
Impact of newly measured 26Al(n, p)26Mg and 26Al(n, α)23Na reaction rates on the nucleosynthesis of 26Al in stars
Umberto Battino, Claudia Lederer-Woods, Marco Pignatari +6
The cosmic production of the short-lived radioactive nuclide 26Al is crucial for our understanding of the evolution of stars and galaxies. However, simulations of the stellar sites…
Impact of Newly Measured Nuclear Reaction Rates on Al Ejected Yields from Massive Stars
Umberto Battino, Lorenzo Roberti, Thomas V. Lawson +2
Over the last three years, the rates of all the main nuclear reactions involving the destruction and production of Al in stars (Al(n, p)Mg, Al(n, )$…
Trans-Fe elements from Type Ia Supernovae. I. Heavy element nucleosynthesis during the formation of near-Chandrasekhar white dwarfs
Umberto Battino, James Keegans, Megan Allen +9
Type Ia supernovae (SNIa) are thermonuclear explosions of white dwarfs in binary systems. They are central to galactic chemical evolution and serve as standardizable candles in cos…
