Coronal activity cycles in nearby G and K stars

by J. Robrade, J.H.M.M. Schmitt, and F. Favata, A&A 543, A84

The results of a long term X-ray monitoring campaign of four G and K stars are reported. This investigation shows that solar-type variations of the coronal activity are apparently a common phenomenon in slowly rotating G and K stars.
