Impact of Sub-2.5 MeV 12C+12CResonances on the Production of Elements from C to Pd in Core-Collapse Supernovae
L. Roberti, S. Palmerini, A. Falla +10
We explore the impact of a more efficient 12C+12C reaction on the structure and nucleosynthesis of massive stars. We calculate non-rotating stellar models with initial masses of 15…
An updated picture of pre-solar history from short-lived radioactive isotopes and inferences on the birth of the Sun
Benjámin Soós, Thomas C. L. Trueman, Andrés Yagüe López +2
We examine the origin of the short-lived radionuclides (SLRs, defined as having half-lives between 0.1 and 100 Ma) present in the early Solar System (ESS) by investigating how pred…
Production of heavy -elements and Ti in Cas A: comparison to abundances from 1D core-collapse supernova models and evidence for Carbon-Oxygen shell mergers
Luca Boccioli, Lorenzo Roberti, Chris L Fryer +3
The merger between the carbon (C) and oxygen (O) shells hours to days before the collapse of a massive star significantly changes its nucleosynthesis, which is reflected in the ele…
Stellar Interpretation of Meteoritic Data and PLotting for Everyone (SIMPLE): Isotope Mixing Lines for Six Sets of Core-Collapse Supernova Models
Marco Pignatari, Mattias Ek, Georgy V. Makhatadze +15
Bulk meteorites and their inclusions exhibit, for many chemical elements, isotopic variability produced by nucleosynthetic events in stars and supernovae before the formation of th…
Strontium-84 Enrichments in Presolar Grains Provide First Evidence of p-process Nucleosynthesis in Core-collapse Supernovae
Ishita Pal, Manavi Jadhav, Danielle Z. Shulaker +9
This study reports detection of rare p-process isotopes within presolar grains. Presolar grains are relic dust grains from dying stars. These microscopic dust particles are found i…
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, )$^…
