Residual Abundances in GALAH DR3: Implications for Nucleosynthesis and Identification of Unique Stellar Populations
Emily J. Griffith, David H. Weinberg, Sven Buder +3
We investigate the [X/Mg] abundances of 16 elements for 82,910 Galactic disk stars from GALAH+ DR3. We fit the median trends of low-Ia and high-Ia populations with a two-process mo…
CNO dredge-up in a sample of APOGEE/Kepler red giants: Tests of stellar models and Galactic evolutionary trends of N/O and C/N
Fiorenzo Vincenzo, David H. Weinberg, Josefina Montalbán +8
Surface abundances of C, N, and O in red giants are affected by processed material mixed into the stars' convective envelopes. Using a sample of stars with elemental ab…
Stellar Migration and Chemical Enrichment in the Milky Way Disc: A Hybrid Model
James W. Johnson, David H. Weinberg, Fiorenzo Vincenzo +6
We develop a hybrid model of galactic chemical evolution that combines a multi-ring computation of chemical enrichment with a prescription for stellar migration and the vertical di…
The Impact of Black Hole Formation on Population Averaged Supernova Yields
Emily J. Griffith, Tuguldur Sukhbold, David H. Weinberg +3
The landscape of black hole (BH) formation -- which massive stars explode as core-collapse supernovae (CCSN) and which implode to BHs -- profoundly affects the IMF-averaged nucleos…
Nucleosynthesis signatures of neutrino-driven winds from proto-neutron stars: a perspective from chemical evolution models
Fiorenzo Vincenzo, Todd A. Thompson, David H. Weinberg +3
We test the hypothesis that the observed first-peak (Sr, Y, Zr) and second-peak (Ba) s-process elemental abundances in low-metallicity Milky Way stars, and the abundances of the el…
