The -Process Alliance: The -Process Enhancement of Stars from Chemodynamically Tagged Groups in the Milky Way Halo
Jessica Merritt Agnos, Charli M. Sakari, Pedro Silva +9
As part of the ongoing work of the -Process Alliance (RPA), detailed abundance measurements of 29 heavy elements in three metal-poor stars, 2MASS J145929813852558, 2MASS J194…
Trials and Tribulations of Chemodynamical Tagging: Investigating the Recovery of Open Clusters in the Gaia DR3-GALAH DR4 Catalog
Nicholas A. Barth, David Mendez, Rana Ezzeddine +5
Chemodynamical tagging has been suggested as a powerful tool to trace stars back to their birth clusters. However, the efficacy of chemodynamical tagging as a means to recover indi…
The -Process Alliance: Enrichment of -process Elements in a Simulated Milky Way-like Galaxy
Yutaka Hirai, Timothy C. Beers, Young Sun Lee +11
We study the formation of stars with varying amounts of heavy elements synthesized by the rapid neutron-capture process (-process) based on our detailed cosmological zoom-in sim…
Stellar Abundances at the Center of Early Type Galaxies with Fine Structure
Nicholas Barth, George C. Privon, Rana Ezzeddine +2
Our understanding of early-type galaxies (ETGs) has grown in the past decade with the advance of full-spectrum fitting techniques used to infer the properties of the stellar popula…
The R-Process Alliance: Chemo-Dynamically Tagged Groups of Halo -Process-Enhanced Stars Reveal a Shared Chemical-Evolution History
Dmitrii Gudin, Derek Shank, Timothy C. Beers +11
We derive dynamical parameters for a large sample of 446 -process-enhanced (RPE) metal-poor stars in the halo and disk systems of the Milky Way, based on data releases from the…
Spectroscopy of the Young Stellar Association Price-Whelan 1: Origin in the Magellanic Leading Arm and Constraints on the Milky Way Hot Halo
David L. Nidever, Adrian M. Price-Whelan, Yumi Choi +7
We report spectroscopic measurements of stars in the recently discovered young stellar association Price-Whelan 1 (PW 1), which was found in the vicinity of the Leading Arm (LA) of…
