Preliminary results for the triple system AV CMi

Abstract

New CCD photometric observations in V, R and I filters of the eclipsing binary AV CMi have been obtained. The complete light curves are analyzed with the Wilson-Devinney code and new geometric and photometric elements are derived. Moreover, 2-year systematic observations of the system revealed the existence of a third body orbiting around one of the components with an approximate period of 0.52 days. The first light elements for this additional component are given and its nature is discussed.
