Abstract (from CDS):

begin{tex}We have examined the short period, double-mode variable star AE Ursae Majoris. Using time series ensemble photometry we have determined six new times of maximum light. We also applied a Fourier decomposition to the data to determine the component frequencies of the light curve. Using our data, along with archival data, we find that the period of AE UMa is continually decreasing at a rate of -1.14×10^{-10} d d^{-1}. However, from the Fourier decomposition we find that the period ratio P_{1}/P_{0} has remained constant at 0.773. We also find that AE UMa is incorrectly classified as a SX Phoenicis star.
