HD5501 is an unusual eclipsing binary star discovered in the course of a survey for classical A-type shell stars. It initially excited interest because it shows variable shell lines. We report here on photometry and spectroscopy of this star carried out over a number of years. We derive the orbital period,estimate the mass of its primary star, and deduce the existence of an accretion disk around the secondary which appears to be a compact object.
