Age and helium content of the open cluster NGC 6791 from multiple eclipsing binary members. I. Measurements, methods, and first results
K. Brogaard, H. Bruntt, F. Grundahl +4
Earlier measurements of the masses and radii of the detached eclipsing binary V20 in the open cluster NGC 6791 were accurate enough to demonstrate that there are significant differ…
Bright Variable Stars in NGC 6819 - An Open Cluster in the Kepler Field
Antonio Talamantes, Eric L. Sandquist, James L. Clem +3
We describe a variability study of the moderately old open cluster NGC 6819. We have detected 4 new detached eclipsing binaries near the cluster turnoff (one of which may be in a t…
A Re-Evaluation of the Evolved Stars in the Globular Cluster M13
Eric L. Sandquist, Mark Gordon, Daniel Levine +1
We present photometry for all bright red giant branch (RGB), horizontal branch (HB), and asymptotic giant branch (AGB) stars within 10' of the center of M13. We find support for th…
