An important new solar paper by Prof Valentina Zharkova and co-authors S. J. Shepherd, S. I. Zharkov & E. Popova  published in ‘Nature’ has incorporated the solar-planetary theory we’ve been researching and advancing here at the talkshop over the last decade. As well as further developing her previous double dynamo theory which now accounts for the last several millennium’s solar grand minima and maxima, she includes discussion of Fairbridge, Mackey, Shirley, Charvatova and Abreu et al’s work. Central to the new hypothesis is the motion of the Sun around the barycentre of the solar system, described as the Solar Inertial Motion [SIM].

Left plot: the example of SIM trajectories of the Sun about the barycenter calculated from 1950 until 210034. Right plot: the cone of expanding SIM orbits of the Sun35 with the top showing 2D orbit projections similar to the left plot. Here there are three complete SIM orbits of the Sun, each of which takes about 179 years. Each solar orbit consists of about eight, 22-year solar cycles35. The total time span is, therefore, three 179-year solar cycles31, or about 600 years. Source: Adapted from Mackey35.

Following my discussion with her at dinner following her talk in London last year, Zharkova now agrees with us that the SIM induced by planetary motion affects sunspot production and solar activity levels.
