Modelling of variability of the chemically peculiar star phi Draconis

Original language description

Context. The presence of heavier chemical elements in stellar atmospheres influences the spectral energy distribution of stars. An uneven surface distribution of these elements, together with flux redistribution and stellar rotation, are commonly believed to be the primary causes of the variability of chemically peculiar (CP) stars. Aims. We aim to model the photometric variability of the CP star. Dra based on the assumption of inhomogeneous surface distribution of heavier elements and compare it to theobserved variability of the star. We also intend to identify the processes that contribute most significantly to its photometric variability. Methods. We use a grid of TLUSTY model atmospheres and the SYNSPEC code to model the radiative flux emerging from the individual surface elements of. Dra with different chemical compositions.
