CMO RC600 discoveries of variable stars

We announce the first results of our search for new variable stars discovered using frames taken with the new automated 60-cm telescope of the Caucasus Mountain Observatory (Sternberg Astronomical Institute, Lomonosov Moscow State University). The ASA RC600 60-cm reflector on German equatorial direct drive mount and absolute encoders (D = 600mm, F = 4200mm) was installed at the Caucasus observatory in spring, 2019 (supported by M.V.Lomonosov Moscow State University Program of Development). It is equipped with an Andor iKon-L (DZ936N-BV) 2048x2048 CCD camera and a set of filters (U, B, V, Rc, Ic, g2, r2, i2, Clear). The frame size is 22 arcminutes to 22 arcminutes.To search for new variable stars, we use the VaST code (Sokolovsky K.V.and Lebedev A.A., 2018, Astronomy and Computing, 22, 28). It is expected that more detailed results will be eventually published by us.

The table presents for the new variable stars: running number; USNO-B1.0 identification; coordinates (GAIA DR2, J2000); variability type; period and epoch for periodic variables; brightness variation range; photometric band. The light curve is also shown.

We are going to append this web page with new data in the course of our reductions of observations from the Caucasus Mountain Observatory's 60-cm telescope and new discoveries of variable stars.
