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…

Deep SDSS optical spectroscopy of distant halo stars I. Atmospheric parameters and stellar metallicity distribution

C. Allende Prieto, E. Fernandez-Alvar, K. J. Schlesinger +14

We analyze a sample of tens of thousands of spectra of halo turnoff stars, obtained with the optical spectrographs of the Sloan Digital Sky Survey (SDSS), to characterize the stell…
