CCD Photometry and Evolutionary Status of the Pulsating Variable CSS J051053.0+071722. (2020). Revista Mexicana De Astronomía Y Astrofísica, 56(1), 129-138. https://doi.org/10.22201/ia.01851101p.2020.56.01.13

Abstract

Multi-color (BVIc) CCD-derived photometric data were acquired for CSS J051053.0+071722, a pulsating variable classified as a high amplitude δ Scuti-type system. Analysis of precise time-series lightcurve data was accomplished using discrete Fourier transformation which revealed a mean fundamental mode (f0) of oscillation at 14.5097 ± 0.0001 d-1 along with two other partial harmonics (2f0 and 4f0). No other statistically significant frequency shared by all bandpasses was resolved following successive pre-whitening of each residual signal. Except for 36 new times-of-maximum light produced from the present study, no other values were found in the literature; therefore, potential secular period changes could not be evaluated. The evolutionary status, age and physical nature of CSS J051053.0+071722 were investigated using the PAdova & TRieste Stellar Evolution Code for generating stellar tracks and isochrones.
