Studying star clusters offers significant advances in stellar astrophysicsdue to the combined power of having many stars with essentially the samedistance, age, and initial composition. This makes clusters excellent testbenches for verification of stellar evolution theory. To fully exploit thispotential, it is vital that the star sample is uncontaminated by stars that arenot members of the cluster. Techniques for determining cluster membershiptherefore play a key role in the investigation of clusters. We present resultson three clusters in the Kepler field of view based on a newly establishedtechnique that uses asteroseismology to identify fore- or background stars inthe field, which demonstrates advantages over classical methods such askinematic and photometry measurements. Four previously identified seismicnon-members in NGC6819 are confirmed in this study, and three additionalnon-members are found -- two in NGC6819 and one in NGC6791. We furtherhighlight which stars are, or might be, affected by blending, which needs to betaken into account when analysing these Kepler data.

An asteroseismic membership study of the red giants in three open clusters observed by Kepler: NGC6791, NGC6819, and NGC6811
