Revised ephemeris for the eclipsing binary RS Ser.
Abstract
RS Ser is an eclipsing binary which has been not subject to publication for a long time. Between 1982 and 1990, visual observations made by GEOS led to the conclusion that the current ephemeris was not valid anymore. In this paper 23 minima observed by GEOS are analyzed, to which were added 4 other minima observed between 1915 and 1954. On the basis of these data, a new ephemeris can be computed: Min I = JD Hel 2,447,355.4509(+/- 16) + 0.5981434(+/-2)*E.
