Abstract

Photographic spectra obtained with the Coudé-spectrograph of the 2-m telescope of BNAO – Rozhen have been used for mapping the elements surface distribution of 36 Lyn. The maps of the distribution of helium, silicon, chromium and magnesium are presented. The results show that helium, silicon and chromium are concentrated mainly in the magnetic equator region. Magnesium is distributed more or less uniformly on the stellar surface.
