Query: Testing Asteroseismic Scaling Relations using Eclipsing Binaries in Star
  Clusters and the Field   The accuracy of stellar masses and radii determined from asteroseismology is
not known! We examine this issue for giant stars by comparing classical
measurements of detached eclipsing binary systems (dEBs) with asteroseismic
measurements from the Kepler mission. For star clusters, we extrapolate
measurements of dEBs in the turn-off region to the red giant branch and the red
clump where we investigate the giants as an ensemble. For the field stars, we
measure dEBs with an oscillating giant component. These measurements allow a
comparison of masses and radii calculated from a classical eclipsing binary
analysis to those calculated from asteroseismic scaling relations and/or other
asteroseismic methods. Our first results indicate small but significant
systematic differences between the classical and asteroseismic measurements. In
this contribution we show our latest results and summarize the current status
and future plans. We also stress the importance of realizing that for giant
stars mass cannot always be translated to age, since an unknown fraction of
these evolved through a blue straggler phase with mass transfer in a binary
system. Rough estimates of how many such stars to expect are given based on our
findings in the open clusters NGC6819 and NGC6791.
