Evolved Eclipsing Binaries and the Age of the Open Cluster NGC 752

We present analyses of improved photometric and spectroscopic observations for two detached eclipsing binaries at the turnoff of the open cluster NGC 752: the 1.01 days binary DS And and the 15.53 days BD +37 410. For DS And, we find M _1 = 1.692 ± 0.004 ± 0.010 M _⊙ , R _1 = 2.185 ± 0.004 ± 0.008 R...
