Hunting The Most Distant Stars in the Milky Way: Methods and Initial Results
John J. Bochanski, Beth Willman, Andrew A. West +2
We present a new catalog of 404 M giant candidates found in the UKIRT Infrared Deep Sky Survey (UKIDSS). The 2,400 deg available in the UKIDSS Large Area Survey Data Release 8…
Star Clusters in M31. V. Evidence for Self-Enrichment in Old M31 Clusters from Integrated Spectroscopy
Ricardo P. Schiavon, Nelson Caldwell, Charlie Conroy +5
In the past decade, the notion that globular clusters (GCs) are composed of coeval stars with homogeneous initial chemical compositions has been challenged by growing evidence that…
A Search for RR Lyrae Stars in Segue 2 and Segue 3
Erin Boettcher, Beth Willman, Ross Fadely +9
We present an extensive search for RR Lyrae stars in and around the ultra-faint Milky Way companions Segue 2 and Segue 3. The former (M_V = -2.5, Belokurov et al. 2009) appears to…
Constraints on mass loss of globular clusters in dwarf galaxies
S. S. Larsen, J. Strader, J. P. Brodie
The Fornax dwarf spheroidal galaxy is well known for its very high globular cluster specific frequency, SN=26. Furthermore, while the field star metallicity distribution peaks at […
