Turbulence in the Solar Wind

Ben Chandran (Univ of New Hampshire) - Apr 28, 2008 at 12:10 pm

Spacecraft observations of velocity and magnetic-field fluctuations in the solar wind provide striking evidence of large-amplitude turbulence in both the fast and slow solar wind. This turbulence is widely believed to play an important role in the heating and generation of the solar wind and the transport of energetic particles. This talk will present an overview of some of the main unsolved problems in this area, including how the excess of anti-Sunward waves affects the turbulence, the role of anisotropy, and the production of "quasi-parallel" waves, whose wavevectors are closely aligned with the background magnetic field. Some recent results on these problems will also be described.

The seminar will be held in 544 Campbell Hall.
