New Times of Minimum and a Period Change of GO Cygni

Two colour (B & V) photoelectric observations of EB-type eclipsing binary GO Cyg were carried out for 15 nights during October and December 1996. Three new times of minimum derived from our own observations are presented. With these and previously published times, the period variation is studied...

description Two colour (B & V) photoelectric observations of EB-type eclipsing binary GO Cyg were carried out for 15 nights during October and December 1996. Three new times of minimum derived from our own observations are presented. With these and previously published times, the period variation is studied, and a continuous period increase of dP/dt ~ 1.51 times 10^(-7) d/yr is estimated from the quadratic ephemeris.
