Annual Review of Astronomy and Astrophysics, 1985
The variety of stellar chromospheric and coronal activity provides a framework for understanding solar and stellar magnetic activity. It is pointed out that the recognition of an 11-yr periodicity within the record of sunspot numbers is a relatively recent discovery of just over a century ago.

The relation between the average magnetic fieldB, the angular velocity Ω, and the periodP of stellar activity cycles is studied. For the calculations we have used Leighton's (1969) model for the solar cycle with the additional assumption that the differential rotation and the cyclonic turbulence (Parker, 1955) (that is the ‘sunspot tilt’ or the ‘α ...

Abstract I review recent results on coronal activity in late-type stars stressing the similarities and differences with respect to solar coronal activity. The emphasis is on recent stellar observations by ROSAT, ASCA and SAX and on prospects for future observations by AXAF and XMM.

Changing stellar activity cycles
Astronomische Nachrichten, 2007AbstractWe investigated continuous long‐term photometric datasets of thirteen active stars, Ca II variability of one single mainsequence star, and 10.7 cm radio data of the Sun, with simple Fourier‐ and time‐frequency analysis. The data reflect the strength of the activity manifested in magnetic spots. All studied stars show multiple (2 to 4) cycles of
