The Twentieth Data Release of the Sloan Digital Sky Survey: First All-Sky BOSS Spectra, eROSITA-SDSS-V Mapper Coordinated Observations, and a Preview of the Local Volume Mapper
SDSS Collaboration, Mojgan Aghakhanloo, David Aguilar +273
The paper describes the twentieth data release (DR20) of the Sloan Digital Sky Survey, providing over 3 million new optical spectra from the SDSS‑V Milky Way, Black Hole, and Local…
OCCAM X. Neutron Capture Abundances with Keck/HIRES & Magellan/MIKE
Natalie R. Myers, Peter M. Frinchaboy, Henrique Reggiani +10
The chemistry of stars provides powerful insight into the history of the Milky Way. With multiple large-sky spectroscopic surveys that are currently available, using chemistry as a…
Hot or Cold? Radial Redistribution of Stars in FIRE Simulations of Milky Way-Mass Galaxies and the Asymmetry of Inward versus Outward Migrators
Cecilia Steel, Andrew Wetzel, Rori Kang +3
Stars can radially redistribute (migrate) within galactic disks. The degree to which this occurs as dynamically `cold' (preserves orbital eccentricity) or `hot' (increases eccentri…
Radial redistribution of stellar orbits in FIRE simulations of Milky-Way-mass galaxies
Matthew A. Bellardini, Fiona McCluskey, Andrew Wetzel +3
A central question in galactic dynamics and galactic archeology is: how much do the orbits of stars redistribute (migrate) after birth? We use the FIRE-2 cosmological zoom-in simul…
The Chemical Homogeneity of Single-Lined Spectroscopic Binaries in Open Clusters
Amaya Sinha, Gail Zasowski, Natalie R. Myers +16
Using SDSS-V DR19 Milky Way Mapper APOGEE data, we measure the impact that close binarity has on surface chemistry across the Hertzsprung-Russell diagram in a broad set of abundanc…
The origin of strong -element bimodalities in FIRE simulations of Milky Way-mass galaxies
Megan Barry, Andrew Wetzel, Sarah Loebman +2
One of the Milky Way's characteristic features is a strongly bimodal distribution of -process elements, such as Mg, at fixed [Fe/H] in stellar abundances. We examine patterns i…
