Characterizing the High-Velocity Stars of RAVE: The Discovery of a Metal-Rich Halo Star Born in the Galactic Disk
K. Hawkins, G. Kordopatis, G. Gilmore +21
We aim to characterize high-velocity (HiVel) stars in the solar vicinity both chemically and kinematically using the fourth data release of the RAdial Velocity Experiment (RAVE). W…
Spectroscopic Signatures of Extra-Tidal Stars Around the Globular Clusters NGC 6656 (M22), NGC 3201 and NGC 1851 from RAVE
Andrea Kunder, G. Bono, T. Piffl +22
Stellar population studies of globular clusters have suggested that the brightest clusters in the Galaxy might actually be the remnant nuclei of dwarf spheroidal galaxies. If the p…
Light, Alpha, and Fe-Peak Element Abundances in the Galactic Bulge
Christian I. Johnson, R. Michael Rich, Chiaki Kobayashi +2
We present radial velocities and chemical abundances of O, Na, Mg, Al, Si, Ca, Cr, Fe, Co, Ni, and Cu for a sample of 156 red giant branch stars in two Galactic bulge fields center…
Light Echoes from Eta Carinae's Great Eruption: Spectrophotometric Evolution and the Rapid Formation of Nitrogen-rich Molecules
J. L. Prieto, A. Rest, F. B. Bianco +18
We present follow-up optical imaging and spectroscopy of one of the light echoes of Carinae's 19th-century Great Eruption discovered by Rest et al. (2012). By obtaining images…
Proper motions for HST observations in three off-axis bulge fields
Mario Soto, Hugo Zeballos, Konrad Kuijken +3
Aims. This is the second in a series of papers that attempt to unveil the kinematic structure of the Galactic bulge through studying radial velocities and proper motions. We report…
Are high velocity peaks in the Milky Way bulge due to the bar?
Zhao-Yu Li, Juntai Shen, R. Michael Rich +2
Recently the commissioning APOGEE observations of the Galactic bulge reported that a significant fraction of stars () are in a cold ( km/s) high velo…
