The Bulge Metallicity Distribution from the APOGEE Survey
The Bulge Metallicity Distribution from the APOGEE Survey
Abstract The Apache Point Observatory Galactic Evolution Experiment (APOGEE) provides spectroscopic information of regions of the inner Milky Way, which are inaccessible to optical surveys. We present the first large study of the metallicity distribution of the innermost Galactic regions based on high-quality measurements for 7545 red giant stars within …
