Description

Turbulence and particle acceleration

9. Turbulent ion scattering by oblique Alfven-cyclotron waves

Dr Yana Maneva (CmPA at KU Leuven)

6/4/15, 3:40 PM

Talk

We perform 2.5D hybrid simulations to study the turbulent heating and acceleration of protons and minor ions in collisionless homogeneous fast solar wind. The focus of this work is wave-particle interactions at the intermediate ion scales, therefore the small-scale electrons are considered as charge-neutralizing isothermal fluid and the electron intertia in our approach is neglected. The...

26. On the (multi)fractal stucture of turbulence from in-situ data in the terrestrial magnetosheath

Dr Marius Echim (IASB)

6/4/15, 4:05 PM

Talk

In-situ measurements of magnetic field fluctuations in the terrestrial magnetosheath revealed differences between the quasi-perpendicular and quasi-parallel shock geometry. In the quasi-parallel case the fluctuations are strongly intermittent as suggested by the scale dependent non-Gaussian wings of the probability distribution functions (PDFs) and the scale dependent behaviour of their fourth...

25. LYRA detections of Aurora events

Dr Athanassios Katsiyannis (Royal Observatory of Belgium)

6/4/15, 4:30 PM

Talk

The Large Yield RAdiometer (LYRA) is an ultraviolet irradiance radiometer on-board ESA's PROBA2 micro-satellite. Since it's launch in 2009 it observes the Sun in four different passbands, chosen for their relevance to solar physics, aeronomy and space weather. Flying on an altitude of 735km, LYRA proved to be an excellent flare monitor and is involved in the analysis the atmospheric...
