[83.09] Starspots on AP063 and AP117 Imaged via Matrix Light-curve Inversion

Matrix Light-curve Inversion (MLI) is a technique for imaging spotted stars using the variations in their light curves. MLI makes no \emph{a priori} assumptions regarding the number of spots, their sizes, or their shapes. The resolution in latitude is improved when light curves obtained through multiple photometric filters are simultaneously inverted. We present images of two stars in the \alpha Persei cluster, AP063 and AP117, based on BVRI CCD photometry obtained at the Michigan-Dartmouth-MIT Observatory from September 18-26, 2001.
