Descripción
The Apache Point Observatory Galactic Evolution Experiment (APOGEE) is
an SDSS-III survey that is obtaining high resolution near-IR (H band)
spectra of 100,000 Milky Way stars in an effort to chemically trace
formation and evolution of Galactic stellar populations. Optical echelle
spectra of a small subset of survey targets have been obtained with the
ARC 3.5m telescope for the purpose of 1) helping to understand and
calibrate the abundance analysis of the APOGEE IR spectra, and 2)
measuring abundances of elements that do not have spectral features in
the APOGEE wavelength region, which will ideally include neutron capture
elements. We present our current sample of ~130 (out of a projected 500)
stars, which is drawn from the brightest APOGEE targets and covers a
range of stellar parameters (temperature, metallicity, and surface
gravity), and compare some optically derived quantities with those from
the APOGEE abundance pipeline.
