Volume 89, Issue 6

Solar-activity plot showing areas and latitudes of sunspots since 1874. A new statistical analysis finds that the irregularities in the solar cycle are the result of the superposition of two constant-amplitude and -phase oscillations on a stochastic background, and are not a manifestation of low-dimensional chaos as had been thought. [P. D. Mininni, D. O. Gómez, and G. B. Mindlin, Phys. Rev. Lett. 89, 061101 (2002)]
