Of approximately 200 exoplanet host stars, we investigate a subset of fifty whose fluxes in the Ca II H and K passbands and b and y photometric passbands have been measured and in several cases, accumulated over a period of years or longer.
The Ca II records from Mount Wilson Observatory's HK Project and highly precise photometric measurements from Tennessee State University's Automated Photoelectric Telescopes at Fairborn Observatory detail variability of surface magnetic features, leading in some cases to a direct measurement of periodicities thought to be associated with rotation.
We discuss findings of rotation in the context of surface magnetic activity, its interannual variability, age and other physical properties of the star. As possible we infer inclination of the stellar rotation axis and its influence on exoplanet detection methods.
This work has been supported by NASA grant JPL-1270064.
