New Photometric Investigations of G-type Contact Binary TU Boo

Abstract: Two sets of CCD photometric observations for contact binary TU Boo were obtained in 2020 and 2021, respectively. Different from its asymmetric light curves published from the literature, our BV RcIc-band curves show that the heights of maximum are almost equal. These distortions of light curves possibly indicate that the components have been active in past 25 yr, but they are stable in the last two years. For total-eclipse binary TU Boo, due to some star-spots on the surface of the components, the physical str… Show more
