Photometric and spectroscopic investigation of nine Cepheids in the Cassiopeia constellation
Original language description
We present new multicolor BVRI photometry and low-resolution spectroscopy of 9 fundamental mode Cepheids in the Cassiopeia constellation. Observations were carried out during the 2017/2018 observing season. We investigated each particular light curve in detail using Fourier decomposition techniques which we compare with the Cepheids from the OGLE project. Using the Gaia parallaxes and the period-luminosity relation we estimated the absolute magnitudes and constructed the Hertzsprung-Russell diagram. Our findings agree with the previously published results except for V824 Cas. This star has small Fourier amplitudes and shows a discrepancy in the absolute magnitudes based on Gaia and period-luminosity relation. We propose that V824 Cas can either be a member of a binary system or is not a fundamental-mode Cepheid but an overtone Cepheid.
