Abstract:
A multifrequency analysis of the SX Phoenicis star BL Camelopardalis is presented on the basis of new high-speed photometry, along with fitting a total of 136 maxima. BL Cam is a multiple periodic pulsator. We find f0 = 25.5768, f1 = 25.2982, f2 = 25.8622, f3 = 31.5912, f4 = 25.1065, f5 = 25.5147 and f6 = 25.6188 cycled-1 together with the harmonics 51.1513 and 76.7268 cycled-1 and combination frequencies f0 + f1, f0 + f2 and f0 + f3. The new frequency solution represents the light curves of BL Cam quite well. The observed minus calculated (O-C) analysis indicates that the fundamental frequency is in good agreement with the results of Fourier analysis.
