An observational study of the high-amplitude delta Scuti star V367 Cam
Original language description
CCD observations of V367 Cam, a high-amplitude 8 Scuti star, were carried out in both V and R band on October 22 and 23 and November 4, 2016. By using the new observed maximum times and the previously reported epochs, a new ephemeris is obtained. Fourier analysis of the light curves yields the main frequency f1 = 8.2242 d(-1) and its second harmonic as 2f1 = 16.4062 d(-1), The pulsation constant specifying the oscillation characteristics of pulsating stars is calculated from physical parameters of V367 Cam. We obtained Q = 0.03814 +/- 0.00409, which demonstrates this star pulsates in single radial fundamental mode. With the derived physical parameters, the evolution status of V367 Cam is determined and also it is shown on H-R diagram against other delta Scuti stars. Furthermore, we made a count of mono-periodic HADS, which are expected to be decreasing in number and turned to be multiperiodic in the advent of high precision photometry and extended data.
