Zeeman-Doppler imaging of active young solar type stars

We present the surface magnetic field and brightness maps of three active solar-type stars (AH Lep, HD 29615, V1358 Ori) using Zeeman-Doppler imaging for high resolution spectropolarimetry obtained with HARPSpol at the ESO 3.6m telescope. Two of the stars show dominance of the poloidal field over the toroidal one and ...
