AV CMi preliminary results from photometric study
Original language description
Preliminary results of one year photometric study of eclipsing binary system AV CMi are presented. Possible low-mass third body on unusual orbit in this system was discovered by Liakos & Niarchos (2010). Our measurements confirmed observed dips of brightness in the light curve called transit of third body. Two measurements were used for identification of host star but neither allows convincing decision. The results are contradictory and thus are opposed of three-body system. Blend of two eclipsing systems in the same position on the sky was proposed for this reason. Accuracy of our astrometric measurements did not allowed to detect an awaited shift in position of centroid during eclipse.
