A Broken Clock Is Right Twice a Day: [Ce/Mg] Is Not a Universal Chemical Clock

Liam O. Dubay, Jennifer A. Johnson, James W. Johnson +14

The ratio of -process to -element enrichment () has been proposed as a ``chemical clock,'' or a means to estimate stellar ages. However, the age-- relation vari…

The Open Cluster Chemical Abundances and Mapping Survey XI. First Gradients from SDSS/MWM BOSS Determined Clusters

Jonah M. Otto, Peter M. Frinchaboy, John Donor +13

The Milky Way Mapper program in the fifth generation of the Sloan Digital Sky Survey (SDSS-V/MWM) has observed millions of stars, thousands of them in open clusters. The Open Clust…

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…

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…

A Galactic Self-Portrait: Density Structure and Integrated Properties of the Milky Way Disk

Julie Imig, Jon A. Holtzman, Gail Zasowski +23

The evolution history of the Milky Way disk is imprinted in the ages, positions, and chemical compositions of individual stars. In this study, we derive the intrinsic density distr…

The Open Cluster Chemical Abundances and Mapping Survey: VIII. Galactic Chemical Gradient and Azimuthal Analysis from SDSS/MWM DR19

Jonah M. Otto, Peter M Frinchaboy, Natalie R. Myers +16

The Open Cluster Chemical Abundances and Mapping (OCCAM) survey seeks to curate a large, comprehensive, uniform dataset of open clusters and member stars to constrain key Galactic…

The Nineteenth Data Release of the Sloan Digital Sky Survey

SDSS Collaboration, Gautham Adamane Pallathadka, Mojgan Aghakhanloo +210

Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial…

A Comprehensive Study of Open Cluster Chemical Homogeneity using APOGEE and Milky Way Mapper Abundances

Amaya Sinha, Gail Zasowski, Peter Frinchaboy +4

Stars in an open cluster are assumed to have formed from a broadly homogeneous distribution of gas, implying that they should be chemically homogeneous. Quantifying the level to wh…
