General remarks
During the century of space exploration astronomical objects
transform continuously into space science objects. The entire
solar system can be viewed today as plasma laboratory where fundamental
astrophysical processes can be studied and tested.
High technology space observations, as available by the Hubble
telescope or the Giant Magellan Telescope under construction, allow
to generalize this view further out in space. Similar
physical processes are encountered in different astrophysical systems
as the sun, supernovae or the early universe. Generalized entropy principles serve
as unifying theoretical concepts between different astrophysical
environments as dark matter and hot plasma content of clustered matter.
Plasma astrophysics is recognized as key discipline in our understanding
of fundamental physical processes as turbulence, scaling properties or
magnetic field generation in galaxies or in the interplanetary and
intergalactic media, phenomena closely related to the problem of
discrete structure formation in the universe.
Theoretical studies focus on
- Astrophysical plasmas, wave-particle interactions, planetary magnetospheres
- Fundamentals of nonextensive systems, power law distributions and entropy principles
- long-range interactions, correlations and memory, PDF's in astrophysical turbulence, scaling properties and intermittency
- Relativistic particle production in astrophysical environments
- nonextensivity of self gravitating systems, hot plasma and dark matter density distributions in clustered matter
- Formation of discrete structure scales in the universe
