"Slow-Mode Turbulence in the Solar Wind and ISM"

by Anjor Kanekar

Friday, April 6, 2012 -- 12:00 p.m.
Large Conference Room, 1207 Energy Research Facility

Advisor:  Professor William Dorland

Solar wind is a collisionless plasma well described by gyrokinetics. The usual turbulence cascade picture of an injection scale, a well-defined inertial range, and dissipation scale applies. Energy flows down from the outer scale to smaller scales, where it finally dissipates into heat. A key, unresolved question is how much energy goes into ions as compared to electrons. This turbulent system has an Alfvenic component and a slow-mode component. The behavior of slow modes in an Alfvenic turbulent bath is still unclear. We present theory and numerical results exploring the nature of this cascade.
