The Binary Populations of Eight Globular Clusters in the Outer Halo of the Milky Way
A. P. Milone, A. F. Marino, L. R. Bedin +6
We analyse color-magnitude diagrams of eight Globular Clusters (GCs) in the outer Galactic Halo. Images were taken with the Wide Field Channel of the Advanced Camera for Survey and…
The cluster ages experiment (CASE). VII. Analysis of two eclipsing binaries in the globular cluster NGC 6362
J. Kaluzny, I. B. Thompson, A. Dotter +2
We use photometric and spectroscopic observations of the detached eclipsing binaries V40 and V41 in the globular cluster NGC 6362 to derive masses, radii, and luminosities of the c…
An HST/WFC3 view of stellar populations on the Horizontal Branch of NGC 2419
M. Di Criscienzo, M. Tailo, A. P. Milone +4
We use images acquired with the Hubble Space Telescope Wide Field Camera 3 and new models to probe the Horizontal Branch (HB) population of the We use images acquired with the Hubb…
Deep near-IR observations of the Globular Cluster M4: Hunting for Brown Dwarfs
A. Dieball, L. R. Bedin, C. Knigge +5
We present an analysis of deep HST/WFC3 near-IR (NIR) imaging data of the globular cluster M4. The best-photometry NIR colour-magnitude diagram (CMD) clearly shows the main sequenc…
