Photometry of the double eclipsing binary CzeV343
Listed in IVOA Registry (Virtual Observatory)
We present the discovery of a possible new quadruple system composed of two unresolved eclipsing binaries (EBs), CzeV343 (V~13.5mag).
Description
We obtained photometric observations of CzeV343 that completely cover the two orbital periods and we successfully model the light curves as the sum of two detached EBs. The two orbital periods, 1.20937 and 0.80693-days, are within 0.1% of a 3:2 ratio.
We speculate that this might be the result of Kozai cycles and tidal friction evolution of quadruple systems.
