CCD PHOTOMETRY, PERIOD ANALYSIS AND EVOLUTIONARY STATUS OF THE PULSATING VARIABLE TYC 3292-1328-1
Multi-color (BVIc) CCD-derived photometric data were acquired from TYC 3292-1328-1, a pulsating variable classified as a high amplitude δ Scuti-type (HADS) system. Analysis of precise time-series lightcurve (LC) data was accomplished using discrete Fourier transformation which revealed a mean fundamental mode (f0) of oscillation at 10.20831±0.00027 d-1 along with five other partial harmonics (2f0 and 6f0). No other statistically significant frequency shared by all bandpasses was resolved following successive pre-whitening of each residual signal. While no other times-of-maximum were found in the literature, 26 new ToMx values are reported herein. The evolutionary status, age and physical nature of TYC 3292-1328-1 were modeled using the PAdova & TRieste Stellar Evolution Code (PARSEC) for generating stellar tracks and isochrones. At this time, all available results for TYC 3292-1328-1 are consistent with its classification as a HADS variable.
