Photoelectric photometry of chemically peculiar stars at the Catania astrophysical observatory. Observatory of HD 2453, HD 71866, HD 72968 and HD 126515.
Abstract
Photoelectric observations of four CP stars are presented which were carried out from 1969 through 1975 at the Catania Astrophysical Observatory in the UBV natural system. For the star HD 2453 a revised value (546.87) of the period is derived from the magnetic field data available in the literature which satisfies the photometric observations. The periods of the stars HD 71866 and HD 72968 are confirmed to be 6.80054 and 11.305 days, respectively. For the long period variable HD 126515 Preston's 130.0 days value, deduced from the magnetic field variations, is shown to be the period of the light variations too.
