| Abstract |
We analyze extensive BVRcI c photometry and radial velocity
measurements for Auner 259 and 537, two detached eclipsing binaries
(DEBs) that are double-lined members of the moderately old ( 2.5 Gyr)
cluster NGC 6819. We present results of binary star modeling to measure
characteristics of the components, focusing on stellar masses and radii
because the binaries reside near the cluster turnoff in a
color-magnitude diagram. The masses and radii will provide constraints
on the cluster age.
