Stellar magnetic-cycle phasing.
GRAY D.F.
Abstract (from CDS):
During magnetic-cycle type variations in dwarf stars, changes in the H & K magnetic activity index precede change in temperature by times ranging from several years at G0 down to near zero at K2. These results are preliminary however because they are based on observations of only three stars.
