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…
The Open Cluster Chemical Abundances and Mapping Survey: IX. Measuring the Effects of Stellar Diffusion in the Open Clusters NGC 752 and Ruprecht 147 using APOGEE
Diogo Souto, Taylor Spoo, Peter M. Frinchaboy +4
A growing understanding of stellar processes that alter surface chemical abundances over time has opened new avenues for using these changes as probes of stellar properties. On the…
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 comprehensive study of the relations between the properties of planetary systems and the chemical compositions of their host stars
Luan Ghezzi, Ellen Costa-Almeida, Verónica Loaiza-Tacuri +1
The giant planet-metallicity correlation revealed that planetary formation depends on the stellar properties. There is growing evidence that it is also valid for smaller hot planet…
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…
Sloan Digital Sky Survey-V: Pioneering Panoptic Spectroscopy
Juna A. Kollmeier, Hans-Walter Rix, Conny Aerts +217
The Sloan Digital Sky Survey-V (SDSS-V) is pioneering panoptic spectroscopy: it is the first all-sky, multi-epoch, optical-to-infrared spectroscopic survey. SDSS-V is mapping the s…
SDSS-V Milky Way Mapper (MWM): ASPCAP Stellar Parameters and Abundances in SDSS-V Data Release 19
Szabolcs Mészáros, Paula Jofré, Jennifer A. Johnson +25
The goal of this paper is to describe the science verification of Milky Way Mapper (MWM) APOGEE Stellar Parameter and Chemical Abundances Pipeline (ASPCAP) data products published…
Signatures of Atmospheric Mass Loss and Planet Migration in the Time Evolution of Short-Period Transiting Exoplanets
Rachel B. Fernandes, Galen J. Bergsten, Gijs D. Mulders +19
Comparative studies of young and old exoplanet populations offer a glimpse into how planets may form and evolve with time. We present an occurrence rate study of short-period (1…
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…
The Brown Dwarf Kinematics Project (BDKP). VI. Ultracool Dwarf Radial and Rotational Velocities from SDSS/APOGEE High-resolution Spectroscopy
Chih-Chun Hsu, Adam J. Burgasser, Christopher A. Theissen +11
We present precise measurements of radial (RV) and projected rotational () velocities, effective temperatures, and surface gravities of a sample of 258 M6 to L2 dwarfs wi…
SDSS-IV from 2014 to 2016: A Detailed Demographic Comparison over Three Years
Amy M. Jones, Rachael L. Beaton, Brian A. Cherinka +24
The Sloan Digital Sky Survey (SDSS) is one of the largest international astronomy organizations. We present demographic data based on surveys of its members from 2014, 2015 and 201…
