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…
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…
Abundance ratios in GALAH DR2 and their implications for nucleosynthesis
Emily Griffith, Jennifer A. Johnson, David H. Weinberg
Using a sample of 70 924 stars from the second data release of the GALAH optical spectroscopic survey, we construct median sequences of [X/Mg] vs. [Mg/H] for 21 elements, separatin…
A Comparison of Stellar and Gas-Phase Chemical Abundances in Dusty Early-Type Galaxies
Emily Griffith, Paul Martini, Charlie Conroy
While we observe a large amount of cold interstellar gas and dust in a subset of the early-type galaxy (ETG) population, the source of this material remains unclear. The two main,…
