New cluster members and halo stars of the Galactic globular cluster NGC 1851
Colin A. Navin, Sarah L. Martell, Daniel B. Zucker
NGC 1851 is an intriguing Galactic globular cluster, with multiple stellar evolutionary sequences, light and heavy element abundance variations and indications of a surrounding ste…
Selecting Sagittarius: Identification and Chemical Characterization of the Sagittarius Stream
E. A. Hyde, S. Keller, D. B. Zucker +11
Wrapping around the Milky Way, the Sagittarius stream is the dominant substructure in the halo. Our statistical selection method has allowed us to identify 106 highly likely member…
Identification of Globular Cluster Stars in RAVE data I: Application to Stellar Parameter Calibration
B. Anguiano, D. B. Zucker, R. -D. Scholz +22
We present the identification of potential members of nearby Galactic globular clusters using radial velocities from the RAdial Velocity Experiment Data Release 4 (RAVE-DR4) survey…
The Parent Populations of 6 groups identified from Chemical Tagging in the Solar neighborhood
Alice C. Quillen, Borja Anguiano, Gayandhi De Silva +4
We estimate the size and distribution of the parent populations for the 6 largest (at least 20 stars in the Solar neighborhood) chemical groups identified in the Chemical Tagging e…
