Chromospheric Ca II emission in nearby F, G, K, and M stars.

Abstract (from CDS):

We present chromospheric Ca II H and K activity measurements, rotation periods, and ages for ∼1200 F, G, K, and M type main-sequence stars from ∼18,000 archival spectra taken at Keck and Lick Observatories as a part of the California and Carnegie Planet Search Project. We have calibrated our chromospheric S-values against the Mount Wilson chromospheric activity data. From these measurements we have calculated median activity levels and derived R'HK, stellar ages, and rotation periods from general parameterizations for 1228 stars, ∼1000 of which have no previously published S-values. We also present precise time series of activity measurements for these stars.
