The ACS Survey of Galactic Globular Clusters. III. The Double Subgiant Branch of NGC 1851
A. P. Milone, L. R. Bedin, G. Piotto +13
Photometry with HST's ACS reveals that the subgiant branch (SGB) of the globular cluster NGC 1851 splits into two well-defined branches. If the split is due only to an age effect,…
Deep ACS Imaging in the Globular Cluster NGC 6397: The Cluster Color Magnitude Diagram and Luminosity Function
Harvey B. Richer, Aaron Dotter, Jarrod Hurley +9
We present the CMD from deep HST imaging in the globular cluster NGC 6397. The ACS was used for 126 orbits to image a single field in two colors (F814W, F606W) 5 arcmin SE of the c…
BVI Photometry and the Luminosity Function of the Globular Cluster M92
N. E. Q. Paust, B. Chaboyer, A. Sarajedini
We present new BVI ground-based photometry and VI space-based photometry for the globular cluster M92 (NGC 6341) and examine luminosity functions in B, V, and I containing over 50,…
A New Color-Magnitude Diagram for Palomar 11
M. S. Lewis, W. M. Liu, N. E. Q. Paust +1
We present new photometry for the Galactic thick disk globular cluster Palomar 11 extending well past the main sequence turn-off in the V and I bands. This photometry shows noticea…
