The New Photometric Study of a Possible Three-body System AV CMi
Original language description
We present new results based on the photometric study of an eclipsing object AV CMi. Liakos and Niarchos (2010) obtained preliminary parameters of the system from photometric measurements and discovered a possible low-mass third body which they placed onan unusual inner orbit around one of the binary components. We confirmed depressions in the light curve and analysed observed changes in the whole light curve. The third body system explanation was tested, but we suggest a new, more realistic, alternative interpretation: a blend of two eclipsing binaries with periods of 2.277751 d and 1.03843 d. Astrometric measurements of the centroid position unfortunately yield no evidence about their angular separation.
