000005158 520__ $$aSince the end of 2018, the Transiting Exoplanet Survey Satellite (TESS)         provides high-quality space data on stellar photometry to the         astronomical community. We present the results of an analysis of         TESS photometric data for known slowly rotating, magnetic,         chemically peculiar (mCP) stars. In general, mCP stars show an         inhomogeneous distribution of elements in their stellar         atmospheres that leads to spectroscopic (line profile) and         photometric (light curve) variations over the rotation period.         In the frame of the oblique magnetic rotator (OMR) model,         patches of enhanced chemical abundance on the stellar surface         reveal the frequency of stellar rotation. Using this approach,         we have compiled a list of slowly rotating mCP stars with         rotation periods longer than two days from the analysis of the         photometric data provided by TESS for the first eight sectors of         observations. Slowly rotating mCP stars usually possess a         hydrodynamically stable stellar atmosphere where a magnetic         field can amplify the process of atomic diffusion and this leads         to the horizontal and vertical stratification of chemical         abundances.
