Recent news from the Sun: from a Sun-grazing mission to the butterfly cycle

Thierry Dudok de Wit (LPCE, Orléans)

In the first part of this seminar we shall get a glimpse of the very recent results from NASA’s Parker Solar Probe mission, which is the first satellite to dive into the multi-million degree solar corona. Parker Solar Probe aims at better understanding one of the major unsolved problems in physics, which is what heats stellar atmospheres so efficiently.

A key player in that heating process is the solar magnetic field. In the second part we shall focus on the periodic reversal of that field. Two centuries of sunspot observations provide us with a unique opportunity to describe that reversal (the so-called butterfly cycle) by means of a low dimensional model that is akin to the Lotka-Volterra model, using here a blind source separation approach.
