Magnetic Surface Images of the BY DRA Star HD 82558
Abstract
We present preliminary results of a new analysis method applied to spectra of the BY Dra star HD 82558. We invert a time series of unpolarized line profiles with different Lande g_eff values to derive both temperature and magnetic field maps of the star. We find strong fields (B > 2 kG) near cool spots and weaker fields elsewhere, with <B> ~ 1 kG.
