Crater 2: An Extremely Cold Dark Matter Halo
Nelson Caldwell, Matthew G. Walker, Mario Mateo +6
We present results from MMT/Hectochelle spectroscopy of red giant candidate stars along the line of sight to the recently-discovered Galactic satellite Crater 2. Modelling the join…
A Chemical Composition Survey of the Iron-Complex Globular Cluster NGC 6273 (M 19)
Christian I. Johnson, Nelson Caldwell, R. Michael Rich +5
Recent observations have shown that a growing number of the most massive Galactic globular clusters contain multiple populations of stars with different [Fe/H] and neutron-capture…
Differences in the rotational properties of multiple stellar populations in M 13: a faster rotation for the "extreme" chemical subpopulation
M. J. Cordero, V. Hénault-Brunet, C. A. Pilachowski +3
We use radial velocities from spectra of giants obtained with the WIYN telescope, coupled with existing chemical abundance measurements of Na and O for the same stars, to probe the…
Before the Bar: Kinematic Detection of A Spheroidal Metal-Poor Bulge Component
Andrea Kunder, R. M. Rich, J. Storm +7
We present 947 radial velocities of RR Lyrae variable stars in four fields located toward the Galactic bulge, observed within the data from the ongoing Bulge RR Lyrae Radial Veloci…
