MHD and Multi-Species Studies of Astrophysical Outflows
With this continuation project we will, based on our previous work, pursue three research paths.
First, we will apply the self-consistent wave-driven model for the turbulent plasma of the ex-
panding solar corona, that we have implemented in the cronos code, to an improved simulation
of coronal mass ejections (CMEs) and their interaction with the solar wind as well as which
each other. Second, we will extend the modelling of the plasma dynamics above the coronal
base by coupling it, via an explicit relation between the initial wave spectrum and photospheric
magnetic structures, to the lower solar atmosphere. Special attention will be given to pho-
tospheric magnetic flux tubes that constitute a very useful concept with which more complex
magnetic structures can be formed. And, third, we will adapt the cronos code such that the
astrophysical scenario of a cosmic ray-driven magnetized galactic wind can be simulated. With
these research activities the project remains tightly connected to other projects as well as to all
three main plasma physical topics of the Research Unit.
