Zugriff:
HD 113816 (IS Vir) is a K0 III RS CVn star. We use high resolution K band spectra obtained with the CHSELL spectrometer to measure the mean magnetic field across the stellar surface. Four strong Ti I lines provide significant sensitivity to magnetic fields, while several magnetically insensitive CO lines provide a check on all other line broadening mechanisms. Our initial analysis reveals a mean field of ~1 kG across the entire stellar surface. We discuss the implications of this measurement.
