Scientific paper

We present our preliminary findings on analysis of Kepler lightcurves for 55 stars near the top of the red giant branch (RGB). Most stars show single strong peaks at low frequencies in their power spectra (slowly pulsating with periods on the order of days to weeks). Other stars show more complex pulsations with multiple periods and a few are likely to be in binary systems. An analysis of the population as a whole will be presented.
