Journal: Monthly Notices of the Royal Astronomical Society
Year: 2012

The multicolour light curves and radial velocities for TYC 1031 1262 1 have been obtained and analysed. TYC 1031 1262 1 includes a Cepheid with a period of 4.15270 0.00061 d. The orbital period of the system is about 51.2857 0.0174 d. The pulsation period indicates that the secular period is increasing at a rate of of 2.46 0.54 min yr -1 . The observed B, V and R magnitudes have been cleaned of the intrinsic variations of the primary star. The remaining light curves that have been obtained consi
