Title: Stellar activity and the rotation of Hyades stars

Abstract

New measurements of rotation periods for Hyades stars, which were obtained from re-analysis of Mount Wilson Observatory Ca II H-K emission flux measurements, are reported. The existence of systematic, color-dependent discrepancies between the measured rotation periods for Hyades stars and those predicted by the Rossby relation as originally calibrated by Noyes et al. 1984 has led to a re-examination of the form of the relationship between chromospheric emission, rotation, and color.
