Lecture Times: Tu 4:30-5:50
Course Information
Over 90% of the visible matter in the Universe is a plasma, that is a dilute
gas of ions, electons, and neutral particles. Thus,
understanding the structure and evolution of the vast majority of astrophysical
systems requires some basic plasma physics. Recent advances
in theory, computational methods, and experimental facilities have led to
new insights into a variety of
plasma processes important in astrophysical systems. This seminar course
is intended to provide an overview of these developments, and introduce
the emerging
discipline of ``Laboratory Plasma Astrophysics". By necessity, the course
will focus on only a few, and arguably the most important,
processes including
- magnetic field amplfication by dynamos
- magnetic reconnection
- magnetorotational and other plasma instabilities
- MHD turbulence
- kinetic MHD
For more information about future research directions in Plasma Astrophysics,

WOPA report.
