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 Apache Point Observatory extra-Galactic Evolution Experiment (APOeGEE): Chemical Abundance Trends for Seven Dwarf Spheroidal Galaxies in the APOGEE Survey
Matthew Shetrone, Rachael L. Beaton, Christian R. Hayes +10
In addition to comprehensive surveys of the Milky Way bulge, disk, and halo, the Apache Point Galactic Evolution Experiment (APOGEE) project observed seven dwarf spheroidal satelli…
Extending the [C/N]-Age Calibration: Using Globular Clusters to Explore Older and Metal-Poor Populations
Taylor Spoo, Katelyn Thomas, Ellie "Kaleo" Toguchi-Tani +8
In the coming years, detailed chemical abundances from large-scale high-resolution spectroscopic surveys will become available for vast numbers of stars across the Milky Way. Previ…
Carbon enrichment in APOGEE disk stars as evidence of mass transfer in binaries
Steve Foster, Ricardo P. Schiavon, Denise B. de Castro +10
Carbon abundances in first-ascent giant stars are usually lower than those of their main-sequence counterparts. At moderate metallicities, stellar evolution of single stars cannot…
