Turbulence in the outer heliosphere

F Fraternale, L Adhikari, H Fichtner, TK Kim… - Space Science …, 2022 - Springer

Constraining ion-scale heating and spectral energy transfer in observations of plasma turbulence

TA Bowen, A Mallet, SD Bale, JW Bonnell, AW Case… - Physical review …, 2020 - APS
We perform a statistical study of the turbulent power spectrum at inertial and kinetic scales
observed during the first perihelion encounter of the Parker Solar Probe. We find that often …

In this study we examine the radial dependence of the inertial and dissipation range indices,
as well as the spectral break separating the inertial and dissipation range in power density …

Strong perpendicular velocity-space diffusion in proton beams observed by parker solar probe

JL Verniero, BDG Chandran, DE Larson… - The Astrophysical …, 2022 - iopscience.iop.org
The SWEAP instrument suite on Parker Solar Probe (PSP) has detected numerous proton
beams associated with coherent, circularly polarized, ion-scale waves observed by PSP's …

Inferred linear stability of parker solar Probe observations using one-and two-component proton distributions

KG Klein, JL Verniero, B Alterman, S Bale… - The Astrophysical …, 2021 - iopscience.iop.org
The hot and diffuse nature of the Sun's extended atmosphere allows it to persist in non-
equilibrium states for long enough that wave–particle instabilities can arise and modify the …
