Scientific paper

We present the results of photometric observations of some stars with planets having small period of circulation. These observations was carried out on the 38-cm Cassegrain telescope (using CCD) of Crimean astrophysical observatory. There is assumption that 11-year-old cycle of solar activity in our Solar system concerned with resonant gravitational influence of giant planets Jupiter and Saturn. We expect to reveal this connection in example of other planetary systems. Therefore the aim of our work was to find the chromospheric activity changes of such stars caused by gravitational influence of giant planets orbiting them. As the result we demonstrate the certain dependences of chromospheric radiation intensity on circulation period of planet near parent star.
