Vlasov-Poisson simulations of electrostatic parametric instability for localized Langmuir wave packets in the solar wind
Pierre Henri, Francesco Califano, Carine Briand +1
Recent observation of large amplitude Langmuir waveforms during a Type III event in the solar wind have been interpreted as the signature of the electrostatic decay of beam-driven…
Low energy Langmuir cavitons: asymptotic limit of weak turbulence
P. Henri, F. Califano, C. Briand +1
Langmuir turbulence is an archetype of wave turbulence in plasma physics. By means of 1D-1V Vlasov-Poisson simulations, we show that coherent structures, called Langmuir cavitons,…
Vlasov simulations of Langmuir Electrostatic Decay and consequences for Type III observations
P. Henri, F. Califano, C. Briand +1
The electrostatic decay enables energy transfer from a finite amplitude Langmuir to a backscattered daughter Langmuir wave and ion acoustic density fluctuations. This mechanism is…
On the Magnetic Prandtl Number Behavior of Accretion Disks
Steven A. Balbus, Pierre Henri
We investigate the behavior of the magnetic Prandtl number (ratio of microscopic viscosity to resistivity) for accretion sources. Generally this number is very small in standard ac…
