Proceedings ArticleDOI
Heating of the solar wind with electron and proton effects
TL;DR: In this paper, the effects of including effects of both protons and electrons on the heating of the fast solar wind through two different approaches were examined, and the authors concluded that incorporating separate proton and electron temperatures and heat conduction effects provided an improved and more complete model of the solar wind.
Journal ArticleDOI
Non-Maxwellianity of Electron Distributions Near Earth's Magnetopause
Daniel B. Graham,Yuri V. Khotyaintsev,Mats André,Andris Vaivads,Alexandros Chasapis,William H. Matthaeus,Alessandro Retinò,Francesco Valentini,Daniel J. Gershman,Daniel J. Gershman +9 more
TL;DR: The outer magnetosphere, magnetosheath, and solar wind are essentially collisionless and particle distributions are not typically in thermodynamic equilibrium and deviate from the norm as discussed by the authors.
Journal ArticleDOI
Energy conversion in turbulent weakly-collisional plasmas: Eulerian Hybrid Vlasov-Maxwell simulations
Oreste Pezzi,Yan Yang,Francesco Valentini,Sergio Servidio,Alexandros Chasapis,William H. Matthaeus,Pierluigi Veltri +6 more
TL;DR: In this paper, the Eulerian hybrid Vlasov-Maxwell (HVM) model is employed to study the balance of energy, focusing on channels of conversion that lead to proton kinetic effects.
Journal ArticleDOI
Parker Solar Probe observations of helical structures as boundaries for energetic particles
F. Pecora,F. Pecora,Sergio Servidio,A. Greco,William H. Matthaeus,D. J. McComas,Joe Giacalone,Colin J. Joyce,T. Getachew,Christina Cohen,R. A. Leske,Mark E. Wiedenbeck,Ralph L. McNutt,Matthew E. Hill,Donald G. Mitchell,E. R. Christian,Edmond C. Roelof,Nathan A. Schwadron,Stuart D. Bale +18 more
TL;DR: In this paper, the authors show observational evidence that intensity variations of solar energetic particles can be correlated with the occurrence of helical magnetic flux tubes and their boundaries, suggesting that the latter act as transport boundaries for particles, consistent with previously developed viewpoints.
Proceedings ArticleDOI
The Interaction of Turbulence with Shock Waves
TL;DR: In this article, the authors discuss the transmission of waves and turbulence across the HTS, both analytically and numerically, in the large plasma beta approximation, and investigate both small amplitude and large amplitude cases.
