Bell et al . Published light curves tend to show depressed shoulders to the primary minimum. This effect is also noticeable in our light curves. It may be due to a disk-like structure around the primary. In the present study a simultaneous solution of new photoelectric U , B , V observations, the ultraviolet light curve formed by integrating low dispersion IUE spectra and collected times of minima collected from the literature, have been used to better our understanding of the TT Aur system.
Open diamonds correspond to the new times of minima.
