Searching for a link between the presence of chemical spots on the surface of HgMn stars and their weak magnetic fields
Abstract
We present the results of mapping the HgMn star AR Aur using the Doppler Imaging technique for several elements and discuss the obtained distributions in the framework of a magnetic field topology.
