V369 Gem: A New Ellipsoidal Variable System With High Level Chromospheric Activity

In this study, we present BVR photometry of V369 Gem in 2006 - 2008. We combined our V data with the data taken from the literature. We analysed all the data together and calculated the new light elements. General features of the light curves were discussed. The light curves were modelled with the Fourier method and the Fourier coefficients calculated. The cos(2theta) term was found to be dominant. The pre-whitened V light curves demonstrated that stellar spot activity also exist. There are generally two minima in the pre-whitened light curves. Thus, there must be two spotted areas, which are separated about 180 deg from each other. As conclusions, we have remarked for the first time that V369 Gem is an ellipsoidal variable with the high level chromospheric activity.
