Abstract:
Analyzing available photometry from the Super WASP and other
databases, we performed the very first light curve analysis of eight
eclipsing binary systems V537 And, GS Boo, AM CrB, V1298 Her, EL Lyn,
FW Per, RU Tri, and WW Tri. All of these systems were found to be
detached ones of Algol-type, having the orbital periods of the order
of days. 722 new times of minima for these binaries were derived and
presented, trying to identify the period variations caused by the
third bodies in these systems.
Description:
The target selection for this paper was rather straightforward. We
have chosen only these systems, which are known to be eclipsing
variables, their orbital period is known, has never been analysed
before and have enough photometric data points for an analysis. Thanks
to the good time coverage provided by the Super WASP survey we used
this database for the whole analysis. All of the analysed systems are
the northern-hemisphere stars (DE>20°) of moderate brightness
(9.5mag<V<13mag) and with the orbital periods ranging from 0.6 to 3.3
days.
