Asteroseismology of Stars in NGC 6791 Using Kepler ``Superstamps''
Abstract
The Kepler space telescope has been a gold mine for asteroseismology thanks to its unprecedented photometric precision and uninterrupted span of observations. One major drawback of Kepler though was that it only read out a few pixels around pre-selected target stars and thus, no information was gathered for most of the stars in the Kepler field of view. Fortunately, for the open clusters NGC 6791 and NGC 6819, Kepler also read out larger ``superstamps'' which contained complete images of the central region of each cluster. These cluster images can be used to study additional stars in the open clusters that were not originally on Kepler's target list. We adapted conventional crowded-field photometric routines to carry out photometry on these superstamps. We present select results from this study in order to show the power and usefulness of using the superstamps. The techniques created for this project will be even more useful in the new K2 mission which will include additional open clusters and, for the first time, globular clusters in its fields of view.
