A photometric study of RT And, light curve solution and high resolution monitoring of its peculiar secondary minimum

Authors
Abstract:
We present the results of UBV photometric observations of the eclipsing binary RT Andromedae, a representative member of the Chromospherically Active Binary Stars (CABS). The aim of this study is the identification of possible short term variations as well as times of minima determination, based on observations in various periods from 2005 to the present. The latter was accomplished using suitable methods to overcome difficulties imposed by the presence of asymmetries. High resolution photometry indicates a total secondary minimum revealing a mid-eclipse brightening. For each light curve, a photometric solution is derived along with the absolute elements of each component, using the WD code.
