Abstract Global solar activity variation mainly occurs over about an 11 yr cycle. However, both longer and shorter periodicities than the cycle are also present in many different indices. The timescales may be up to hundreds of years, while for global variability could within 0.5–2 yr, which include, e.g., from Rieger-type periods (150–160 days) quasi-biennial oscillations 2 yr. most likely ori...

A very simple definition of Ising dusters was introduced by Rieger which joins spins with an average individual magnetization opposite to the global magnetization. Involving percolation methods we get very good agreements between the critical temperatures and the percolation thresholds of diluted and undiluted Ising systems in various dimensions.

Context. The Rieger cycles were discovered in the Sun as a specific 154-day periodicity of flare occurrence; they strongly influence terrestrial space weather. This phenomenon is far from being understood. Various proposed mechanisms for this need further verification stars with stellar parameters different those Sun. Aims. In work, we study Rieger-type cycle (RTC) periods P RTC activity survey...
