XX Cep BVRI light curves
Listed in IVOA Registry (Virtual Observatory)
We obtained CCD photometric observations of the Algol-type semidetached binary XX Cephei (XX Cep) during 15 nights from 2002 September 17 to 2003 February 2, and also on 2005 January 21.
Description
Except for those data taken on the last night of the concentrated observing season, the 3881 measurements were obtained over an interval of only 106 nights. From these data, four new times of minimum light were calculated.
The (O-C) diagram formed from all available timings, and thus the orbital period of the system, can be partly represented as a beat effect between two cyclical variations with different periods (P1'=42yr, P2'=181yr) and amplitudes (K1=0.015d, K2=0.103d), respectively. Both physical and non-physical interpretations of these cycles were investigated.
