On May 13, the biggest European astronomy fair ATT (Astronomie und Techniktreff) will take place in Essen (Germany). Today the organisation presented the program - see this link
Beside the many exibitors and meeting astronomy friends, I'm looking out to the lecture of Ulrich von Kusserow.
Formation of the magnetic solar system (Ulrich von Kusserow)
In this lecture, the variety of possible influencing factors of cosmic magnetic fields on the formation and early development of our solar system and other sun-like star systems is explained as clearly as possible using colorful illustrations, animations and video sequences. After a short introduction, the central events in the course of the history of knowledge acquisition on this topic will be presented in more detail. The following section deals with the great current importance of magnetic processes in the interior and atmosphere of the sun, in the surrounding heliosphere shaped by the magnetic solar wind, and the fascinating processes in the magnetospheres of the planets and moons, asteroids and comets in our solar system .
The fourth section explains how so-called accretion disks form around such stars, in which magnetic turbulence and, in particular, magnetized winds emanating from these disks ensure the effective removal of angular momentum and thus the transport of matter to increase the stellar mass and the formation of the planets. In the last section, the possible magnetic influence on the increasing compression and migration of dust particles, rock-like objects and planetesimals and finally on the formation of the magnetic planets in our solar system is considered.
