Description

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.
