Graphs on Multifractal Analysis of the Variability of Sunspots (image) The Henryk Niewodniczanski Institute of Nuclear Physics Polish Academy of Sciences Share Print E-Mail Caption Analysis of multifractals, conducted by the Institute of Nuclear Physics of the Polish Academy of Sciences in Kraków, Poland, suggest the existence of an unknown mechanism on the Sun, influenced by changes in the number of sunspots. Graphs on multifractal analysis of the variability of sunspots show a clear right-handed asymmetry. The horizontal axis represents the degree of singularity, and the vertical axis shows the spectrum of singularity.
