Popis | Discovery of a new eclipsing binary system CzeV615 = BD+09 3111 in the vicinity of an RR Lyrae star, AT Ser, is presented. The variability of the star was detected from CCD measurements with a small telescope. Observations from ASAS-3, NSVS and WISE sky-surveys were used for follow-up analysis. A brightness variation with a period of 1.4869803 d and an amplitude of about 0.1 mag was found. The shapes of light curves in the optical and infrared bands indicate a similar surface temperature for both components. Nevertheless, a period of half the value of the presented period can not be ruled out using the mentioned data. |
