Local proton heating at magnetic discontinuities in Alfvenic and non-Alfvenic solar wind
C. A. Gonzalez, J. L. Verniero, R. Bandyopadhyay +1
We investigate the local proton energization at magnetic discontinuities/intermittent structures and the corresponding kinetic signatures in velocity phase space in Alfvénic and no…
Evolution of MHD turbulence in the expanding solar wind: residual energy and intermittency
Chen Shi, Nikos Sioulas, Zesen Huang +3
We conduct 3D magnetohydrodynamic (MHD) simulations of decaying turbulence in the solar wind context. To account for the spherical expansion of the solar wind, we implement the exp…
Dispersive and kinetic effects on kinked Alfvén wave packets: a comparative study with fluid and hybrid models
Anna Tenerani, Carlos González, Nikos Sioulas +2
We investigate dispersive and kinetic effects on the evolution of a two-dimensional kinked Alfvén wave packet by comparing results from MHD, Hall-MHD and hybrid simulations of a lo…
Particle-in-cell simulations of Alfvén wave parametric decay in a low-beta plasma
C. A Gonzalez, Maria Elena Innocenti, Anna Tenerani
We study the parametric decay instability of parallel propagating Alfvén wave in a low-beta plasma using one-dimensional fully kinetic simulations. We focus for the first time on t…
Proton and electron temperatures in the solar wind and their correlations with the solar wind speed
Chen Shi, Marco Velli, Roberto Lionello +8
The heating and acceleration of the solar wind remains one of the fundamental unsolved problems in heliophysics. It is usually observed that the proton temperature is highly…
Parker Solar Probe: Four Years of Discoveries at Solar Cycle Minimum
N. E. Raouafi, L. Matteini, J. Squire +54
Launched on 12 Aug. 2018, NASA's Parker Solar Probe had completed 13 of its scheduled 24 orbits around the Sun by Nov. 2022. The mission's primary science goal is to determine the…
