Neutron Economy and Freeze-out Dynamics in the Late-Time Cold r-Process
Mengke Li, Bradley Meyer
Standard r-process models often treat the freeze-out phase as a passive, uniform smoothing of the global abundance pattern. We demonstrate, however, that the final pattern is inste…
Heavy element nucleosynthesis in rotating proto-magnetar winds
Tejas Prasanna, Matthew S. B. Coleman, Todd A. Thompson +3
The astrophysical origin of elements synthesized through the rapid neutron capture process (process) is a long standing mystery. The hot and dense environments of core-collapse…
High-temperature Tl decay clarifies Pb dating in early Solar System
G. Leckenby, R. S. Sidhu, R. J. Chen +56
Radioactive nuclei with lifetimes on the order of millions of years can reveal the formation history of the Sun and active nucleosynthesis occurring at the time and place of its bi…
Presolar Grains As Probes of Supernova Nucleosynthesis
Nan Liu, Maria Lugaro, Jan Leitner +2
We provide an overview of the isotopic signatures of presolar supernova grains, specifically focusing on 44Ti-containing grains with robustly inferred supernova origins and their i…
Explosive Nucleosynthesis in Core-Collapse Type II Supernovae: Insights from new C, N, Si, and Al-Mg isotopic compositions of presolar grains
Nan Liu, Conel M. O'D. Alexander, Bradley S. Meyer +3
We report C, N, Si, and Al-Mg isotope data for 39 presolar X silicon carbide (SiC) and four silicon nitride grains - a group of presolar grains that condensed in the remnants of co…
Bayesian averaging for ground state masses of atomic nuclei in a Machine Learning approach
M. R. Mumpower, M. Li, T. M. Sprouse +3
We present global predictions of the ground state mass of atomic nuclei based on a novel Machine Learning (ML) algorithm. We combine precision nuclear experimental measurements tog…
