    Abundances of disk and bulge giants from high-resolution optical spectra. I. O, Mg, Ca, and Ti in the solar neighborhood and Kepler field samples
    Context. The Galactic bulge is an intriguing and significant part of our Galaxy, but it is hard to observe because it is both distant and covered by dust in the...

    Abundances of disk and bulge giants from high-resolution optical spectra. II. O, Mg, Co, and Ti in the bulge sample
    Context. Determining elemental abundances of bulge stars can, via chemical evolution modeling, help to understand the formation and evolution of the bulge...

    Abundances of iron-peak elements in 58 bulge spheroid stars from APOGEE
    Context. Stars presently identified in the bulge spheroid are probably very old, and their abundances can be interpreted as due to the fast chemical enrichment...

    Abundances of light metals and NI in a sample of disc stars
    High resolution, high S/N spectra obtained using RETICON and CCD detectors are used to determine the abundances of Al, Si, Ca, Ni and Fe in 23 disc stars in the...

    Abundances of Na, Mg and Al in stars with giant planets
    We present Na, Mg and Al abundances in a set of 98 stars with known giant planets, and in a comparison sample of 41 “single” stars. The results show that the [X...

    Abundances of P, S, and K in 58 bulge spheroid stars from APOGEE
    Context. We have previously studied several elements in 58 selected bulge spheroid stars, based on spectral lines in the H band. We now derive the abundances of...

    Abundances of refractory elements in the atmospheres of stars with extrasolar planets
    Aims.This work presents a uniform and homogeneous study of chemical abundances of refractory elements in 101 stars with and 93 without known planetary...

    Abundances, Stellar Parameters, and Spectra from the SDSS-III/APOGEE Survey
    The SDSS-III/Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey operated from 2011–2014 using the APOGEE spectrograph, which collects high...

    Accelerated quenching and chemical enhancement of massive galaxies in a z ≈ 4 gas-rich halo
    Stars in galaxies form when baryons radiatively cool down and fall into dark matter-dominated gravitational wells. Eventually, star formation quenches as gas is...
