Abstract Parker Solar Probe is the first mission to probe in situ the innermost heliosphere,
revealing an exceptionally dynamic and structured outer solar corona. Its payload includes a …

Shock waves are associated with multiple powerful coherent radio emissions within the
heliosphere and local interstellar medium. The radio emissions definitely driven by shocks …

In space plasmas, electron populations exhibit non-equilibrium velocity distributions with
high-energy tails that are reproduced by the Kappa power-laws and contrast with the …

Langmuir turbulence excited by electron flows in solar wind plasmas is studied on the basis
of numerical simulations. In particular, nonlinear wave decay processes involving ion-sound …

Solar radio emissions are electromagnetic waves emitted in the solar wind as a
consequence of electron beams accelerated during solar flares or interplanetary shocks …

We present observational evidence that the polarization of Langmuir waves associated with
solar type III radio bursts is organized by the speed of the driving electron beam. Seven …

About 40% of the waveforms observed by STEREO during type III solar radio bursts exhibits
Langmuir beating and have split spectral peaks, suggestive of decay into product Langmuir …

Langmuir ponderomotive effects are nonlinear effects that enable to couple the electron and
ion dynamics in space plasmas. The main difficulty to provide observational evidence of …

We present observational evidence for the oscillating two stream instability (OTSI) and
spatial collapse of Langmuir waves in the source region of a solar type III radio burst. High …

Since the very beginning of the space venture, discrepancies between hydrodynamic
models and observations have raised the attention to the kinetic effects taking place in the …
