Magnetic Doppler Imaging of Active Stars
Abstract
We present a new magnetic Doppler imaging code which aims at self-consistent temperature and magnetic mapping of cool active stars. Our magnetic imaging procedure is unique in its capability to interpret rotational modulation of individual spectral features in all four Stokes parameters. We discuss performance and intrinsic limitations of our magnetic Doppler imaging method and present results of the simultaneous reconstruction of temperature spots and magnetic field on active star II Peg.
