Talk Title: "Plasma Turbulence in the Solar Wind"

Abstract:

Turbulence is a ubiquitous phenomenon in plasmas, from laboratory devices such as tokamaks, to space and astrophysical plasmas such as the solar wind, interstellar medium and accretion disks. However, in many respects it is poorly understood, despite the importance it plays in all of these plasmas. In the solar wind, spacecraft are now providing in situ measurements with sufficient resolution that significant progress has be made in understanding the cascade of turbulent energy from large system size scales down to kinetic dissipation scales. In this talk, I will present an overview of our current understanding of turbulence in the solar wind and will then focus on recent observational progress we have made in revealing the nature of the turbulence and dissipation at plasma kinetic scales. I will discuss the implications of these results for solar wind heating and applications to other turbulent plasmas.
