Abstract:
The surface distribution of five elements: iron, chromium, titanium,
magnesium and manganese on the magnetic A0pCr star epsilon UMa, have
been calculated using the Doppler imaging technique. We found that iron,
chromium and manganese are correlated with the assumed dipole magnetic field
geometry of this star, which is apparently not the case of magnesium
and titanium.
