Nature of Transonic Sub-Alfvénic Turbulence and Density Fluctuations in the Near-Sun Solar Wind: Insights from Magnetohydrodynamic Simulations and Nearly-Incompressible Models
Giuseppe Arrò, Hui Li, Gary P. Zank +2
Recent Parker Solar Probe measurements have revealed that solar wind (SW) turbulence transits from a subsonic to a transonic regime near the Sun, while remaining sub-Alfvénic. Thes…

Parallel and perpendicular diffusion of energetic particles in the near-Sun solar wind observed by Parker Solar Probe
Nibuna Siranjeevi Madam Subashchandar, Lingling Zhao, Andreas Shalchi +6
We investigate energetic particle diffusion in the inner heliosphere (approximately 0.06-0.3 AU) explored by Parker Solar Probe (PSP). Parallel (kappa_parallel) and perpendicular (…
