The Sun is our nearest star; it is also the most important star that determines life on Earth. A
large variety of phenomena observed on the Sun's surface, with potential impact on Earth, is …

The complex dynamics of solar activity appear to be characterized by a number of
oscillations ranging from monthly to multimillennial timescales, the most well-known of which …

These lecture notes are based on a tutorial given in 2017 at a plasma physics winter school
in Les Houches. Their aim is to provide a self-contained graduate-student level introduction …

This article deals with the prediction of the upcoming solar activity cycle, Solar Cycle 25. We
propose that astronomical ephemeris, specifically taken from the catalogs of aphelia of the …

Commenting the 11-year sunspot cycle, Wolf (1859, MNRAS 19, 85–86) conjectured that
“the variations of spot-frequency depend on the influences of Venus, Earth, Jupiter, and …

In this paper I examine whether external forcing of the solar dynamo on long timescales can
produce detectable signal in the form of long term modulation of the magnetic cycle. This …

Cyclic activity on the Sun and stars is primarily explained by the generation of the magnetic
field by a dynamo mechanism, which converts the energy of the poloidal field into the energy …

Can atmospheric waves in planet-hosting solar-like stars substantially resonate to tidal
forcing, perhaps at a level of impacting the space weather or even being dynamo-relevant …

We propose a self-consistent explanation of Rieger-type periodicities, the Schwabe cycle,
and the Suess-de Vries cycle of the solar dynamo in terms of resonances of various wave …

Magnetic fields are observed in massive Ap/Bp stars and are presumably present in the
radiative zone of solar-like stars. To date, there is no clear understanding of the dynamics of …
