BVR photometry of a newly identified RS CVn binary star HD 61396

Abstract

BVR photometry of a recently identified RS CVn binary star HD 61396, carried out during 2001, is presented. The new photometry reveal significant evolution in the shape and amplitude of light curve when compared with those reported earlier by Padmakar et al.(2000). The traditional two-starspot model has been used to obtain the spot parameters from the observed light curve. Changes in the spot area and their location on the stellar surface are discernible from the extracted parameters from the new photometry.
