UBVR light curves of ER Vul and RT And
Listed in IVOA Registry (Virtual Observatory)
We present the light curves of chromospherically active binary systems, RT And and ER Vul, obtained during 1995-1998 in BV/UBVR filters at the Ankara University Observatory and the TUBITAK National Observatory.
Description
In addition, the spot distributions for these systems are investigated by using the Wilson-Devinney program. Outside of the eclipses, the light curve variations are attributed to large cool spots located on one of components of the systems.
While three spots were located on the primary component in the case of RT And, the location of three spots were considered on the secondary star in the case of ER Vul. From the spot motions in longitudes between 1995 and 1998, it was inferred that the migration period of the distortion wave has at value of 6.6 years for RT And.
