Collisionless Plasma Shocks. Field Generation and Particle Acceleration
T. Haugboelle, C. B. Hededal, J. T. Frederiksen +1
Gamma ray bursts are among the most energetic events in the known universe. A highly relativistic fireball is ejected. In most cases the burst itself is followed by an afterglow, e…
Magnetic Field Generation and electron acceleration in Collisionless Shocks
C. B. Hededal, J. Trier Frederiksen, T. Haugboelle +1
Using a three dimensional relativistic particle-in-cell code we have performed numerical experiments of plasma shells colliding at relativistic velocities. Such scenarios are found…
Oscillation power spectra of the Sun and of Alpha Cen A: observations versus models
R. Samadi, M. J. Goupil, F. Baudin +4
Hydrodynamical, 3D simulations of the outer layers of the Sun and Alpha Cen A are used to obtain constraints on the properties of turbulent convection in such stars. These constrai…
Collisionless Shocks -- Magnetic Field Generation and Particle Acceleration
J. Trier Frederiksen, C. B. Hededal, T. Haugboelle +1
We present numerical results from plasma particle simulations of collisionless shocks and ultra-relativistic counter-streaming plasmas. We demonstrate how the field-particle intera…
Seismic diagnostics on stellar convection treatment from oscillation amplitudes of p-modes
R. Samadi, M. J. Goupil, Y. Lebreton +2
The excitation rate P of solar p-modes is computed with a model of stochatic excitation which involves constraints on the averaged properties of the solar turbulence. These constra…
Consequences of the non gaussian character of the stochastic excitation for solar-type oscillations
R. Samadi, A. Nordlund, R. F. Stein +2
Our recent study, based on a 3D numerical simulation, suggested that the stochastic excitation of solar p-modes has a non gaussian nature and a non gaussian model was proposed whic…
