Evidence from Disrupted Halo Dwarfs that -process Enrichment via Neutron Star Mergers is Delayed by Myrs
Rohan P. Naidu, Alexander P. Ji, Charlie Conroy +10
The astrophysical origins of -process elements remain elusive. Neutron star mergers (NSMs) and special classes of core-collapse supernovae (rCCSNe) are leading candidates. Due t…
Detailed elemental abundances of binary stars: Searching for signatures of planet formation and atomic diffusion
Fan Liu, Bertram Bitsch, Martin Asplund +5
Binary star systems are assumed to be co-natal and coeval, thus to have identical chemical composition. In this work we aim to test the hypothesis that there is a connection betwee…
Chemical Cartography with APOGEE: Mapping Disk Populations with a Two-Process Model and Residual Abundances
David H. Weinberg, Jon A. Holtzman, Jennifer A. Johnson +33
We apply a novel statistical analysis to measurements of 16 elemental abundances in 34,410 Milky Way disk stars from the final data release (DR17) of APOGEE-2. Building on recent w…
How Many Elements Matter?
Yuan-Sen Ting, David H. Weinberg
Some studies of stars' multi-element abundance distributions suggest at least 5-7 significant dimensions, but others show that many elemental abundances can be predicted to high ac…
