"Slow Mode Turbulence in the Solar Wind and ISM"
Advisor: William Dorland
Solar wind is a collisionless plasma well described by gryokinetics. The usual turbulence cascade picture of an injection scale, a well defined inertial range, and a dissipation scale applies. Energy flows down from the outer scales 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.
