An Updated Line List for NUV Spectral Synthesis in Evolved Stars: Redetermination of the Beryllium Abundance in the Solar Photosphere
Joleen K. Carlberg,Katia Cunha,Verne V. Smith,José-Dias do Nascimento,José-Dias do Nascimento +4 more
TL;DR: In this article, a new line list for synthesizing spectra in the near-ultraviolet was constructed by using the Sun, Arcturus, and Pollux as benchmark stars to explore potential sources of missing continuous opacity and line absorption.
Journal ArticleDOI

Munoz,Christian Nitschelm,Alexandre Roman-Lopes,Olga Zamora,Olga Zamora +25 more
TL;DR: In this paper, the authors studied the multiple populations of $\omega$ Cen by using the abundances of Fe, C, N, O, Mg, Al, Si, K, Ca, and Ce from the high-resolution, high signal-to-noise spectra of 982 red giant stars observed by the SDSS-IV/APOGEE-2 survey.
Journal ArticleDOI
Fluorine Abundances in the Galactic Disk
Rafael Guerço,Katia Cunha,Verne V. Smith,Christian R. Hayes,Carlos Abia,David L. Lambert,Henrik Jönsson,Henrik Jönsson,Nils Ryde +8 more
TL;DR: In this article, the chemical evolution of fluorine is investigated in a sample of Milky Way red giant stars that span a significant range in metallicity from [Fe/H] ∼-1.3 to 0.0 dex.
Journal ArticleDOI

Majewski,Christian Moni Bidin,Christian Nitschelm,Alexandre Roman-Lopes,Ricardo P. Schiavon,Verne V. Smith,Jennifer Sobeck +26 more
TL;DR: In this paper, the authors present stellar age distributions of the Milky Way bulge region using ages for ∼6000 high-luminosity (log(g) 8 Gyr) stars.

Pinsonneault,Donald P. Schneider,Matthew Shetrone,Keivan G. Stassun,Ryan Terrien,Olga Zamora,B. Stringfellow,Richard R. Lane,Christian Nitschelm,Bárbara Rojas-Ayala +20 more
TL;DR: In this paper , a sample of M dwarfs using high-resolution, near-infrared H-band spectra from the Sloan Digital Sky Survey-IV/Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey was used to investigate Galactic chemical evolution via trends of [X/Fe] as a function of [Fe/H].
