The relation between rotation and magnetic activity on lower main sequence stars as derived from chromospheric indicators
Abstract
The nature of the relationship between magnetic-field-induced chromospheric emission of lower-main-sequence stars in the H and K lines of Ca II and stellar rotation is investigated in a survey of observational data, which are plotted against each other in a series of graphs. Parameters such as spectral type, rotation period, H+K flux, and stellar age are considered, and particular attention is devoted to the gap in the plot of chromospheric emission versus (B-V) constructed by Vaughan and Preston (1980).
