Photometric Study of the Near Critical Contact System, GSC 3355 0394

The First Photometric Investigation of the Neglected Contact Binary LP Comae

“…The different heights of the two light maxima between phase 0.25 and 0.75 in the top panel of Figure 1 could be caused by the existence of dark spots on the common convective envelope. These models of dark spots were used earlier by some studies (e.g., Bell et al 1990;Samec et al 2010;Zhu et al 2012). To explain the O'Connell effect, the presence of dark spot activity on the photospheric surface of two components is displayed in this work.…”
