A STATISTICAL ANALYSIS OF FLARE EVENTS AND ITS IMPLICATIONS CONCERNING THE SUN'S INTERNAL ROTATION,

Abstract

A series of 1119 flares of importance > or = 2, distributed over 6 1/2 years of solar cycle 19, has been spectrum-analyzed in longitude by a statistical procedure based on the maximum-likelihood principle. Modulation of order 25 percent is found at two independent rotation rates with synodic periods 28.80 and 31.63 days. It is proposed that these spectral components in the flare distribution are due to, and provide measurements of, the rigid-body rotation of the radiative core and of the bulk of the convective zone, respectively. In addition to their implication concerning the solar interior, these results are relevant to flare prediction. (Author)
