Solar activity is characterized by specific oscillations known in the literature as the cycles of Bray-Hallstatt (2100-2500 yr), Eddy (800-1200 yr), Suess-de Vries (200-250 yr), Jose (155-185 yr), Gleissberg (80-100 year), the 55-65 yr cluster, the 40-50 yr cluster and others. Herein I show that these oscillations emerge from a specific set of planetary harmonics - the orbital invariant inequalities - produced by the Jovian planets (Jupiter,Saturn, Uranus and Neptune). The result suggests that solar activity is modulated by harmonic planetary forcings.

Abstract
Solar activity is characterized by specific oscillations known in the literature as the cycles of Bray-Hallstatt (2100-2500 yr), Eddy (800-1200 yr), Suess-de Vries (200-250 yr), Jose (155-185 yr), Gleissberg (80-100 year), the 55-65 yr cluster, the 40-50 yr cluster and others. Herein I show that these oscillations emerge from a specific set of planetary harmonics - the orbital invariant inequalities - produced by the Jovian planets (Jupiter,Saturn, Uranus and Neptune). The result suggests that solar activity is modulated by harmonic planetary forcings.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
