UBVRI Photometric Analysis of the Solar-Type Eclipsing Binary TYC 3034-299-1

الملخص EN

TYC 3034-0299-1 (CVn) is a magnetically active, contact binary, ROTSE variable.

UBVRcIc light curves are presented along with a period study and a simultaneous UBVRI light curve solution.

Our light curves show eclipse amplitudes of 0.72 and 0.62 mags (V) in the primary and secondary eclipses.

Modeled results include a dark spot region, found at longitude 51°, a 24% Roche lobe fill-out, and a mass ratio of 0.48.

A total eclipse is found to occur in the secondary eclipse making TYC 3034-0299-1 a W-type (less massive star is hotter) W UMa variable.
