Chemical Abundances of M-dwarfs from the APOGEE Survey. I. The Exoplanet Hosting Stars Kepler-138 and Kepler-186
Diogo Souto, Katia Cunha, D. A. Garcia-Hernandez +18
We report the first detailed chemical abundance analysis of the exoplanet-hosting M-dwarf stars Kepler-138 and Kepler-186 from the analysis of high-resolution ( 22,500) $…
Chemical Abundances in a Sample of Red Giants in the Open Cluster NGC 2420 from APOGEE
Diogo Souto, Katia Cunha, Verne Smith +20
NGC 2420 is a 2 Gyr-old well-populated open cluster that lies about 2 kpc beyond the solar circle, in the general direction of the Galactic anti-center. Most previous abundan…
Examining the relationships between colour, , and [M/H] for APOGEE K and M dwarfs
Sarah J. Schmidt, Erika L. Wagoner, Jennifer A. Johnson +4
We present the effective temperatures (), metallicities, and colours in SDSS, 2MASS, and WISE filters, of a sample of 3834 late-K and early-M dwarfs selected from the…
Discovery of a Metal-Poor Field Giant with a Globular Cluster Second-Generation Abundance Pattern
J. G. Fernández-Trincado, A. C. Robin, E. Moreno +31
We report on detection, from observations obtained with the APOGEE spectroscopic survey, of a metal-poor ([Fe/H] dex) field giant star with an extreme Mg-Al abundance rati…
Chemical abundance gradients from open clusters in the Milky Way disk: results from the APOGEE survey
Katia Cunha, Peter M. Frinchaboy, Diogo Souto +23
Metallicity gradients provide strong constraints for understanding the chemical evolution of the Galaxy. We report on radial abundance gradients of Fe, Ni, Ca, Si, and Mg obtained…
