Intermittent turbulence as the driver of stochastic heating in the near-Sun solar wind

Tamar Ervin, Trevor A. Bowen, Alfred Mallet +9

Understanding the mechanism by which the energy is dissipated at small scales to heat the outer corona and expanding solar wind, is a primary goal of the Parker Solar Probe (PSP) m…

Measured energy exchange in coronal hole solar wind from its solar origins to the heliosphere

Yeimy J. Rivera, Alin R. Paraschiv, Samuel T. Badman +33

Coordinated ground- and space-based remote observations are used to provide a comprehensive, multi-perspective view of the solar atmosphere that we connect with in situ measurement…

Wave Emission and Absorption in a Near-Sun Proton-Cyclotron Wave Storm

Kristopher G Klein, Daniel Verscharen, Mihailo Martinovic +5

Quantification of energy transport and dissipation in weakly collisional heliospheric plasmas that are far from local thermodynamic equilibrium is an outstanding scientific problem…

Direct Measurement of Polar Coronal Hole-like Solar Wind in its Acceleration Phase

Samuel T. Badman, Yeimy J. Rivera, Michael L. Stevens +38

The early evolution of fast polar coronal hole (PCH) solar wind remains largely unconstrained by in situ measurements. In March 2025, Parker Solar Probe (Parker) at its closest app…

Direct Measurement of Diffusion Coefficients: Evidence for Diffusive Stochastic Heating in Collisionless Plasmas

Tamar Ervin, Trevor A. Bowen, Alfred Mallet +7

Open questions in collisionless plasma dissipation can be addressed using space-based observations in different astrophysical environments, with implications for both astrophysical…

Free Energy Sources of Ion-scale Waves Observed by Parker Solar Probe

Niranjana Shankarappa, Kristopher G. Klein, Mihailo M. Martinović +6

Parker Solar Probe (PSP) observes abundant circularly polarized ion-scale waves throughout the inner heliosphere. These waves are a signature of the interplay between plasma microi…

On the Propagation and Damping of Alfvenic Fluctuations in the Outer Solar Corona and Solar Wind

Nikos Sioulas, Marco Velli, Chen Shi +17

We analyze \textit{Parker Solar Probe} and \textit{Solar Orbiter} observations to investigate the propagation and dissipation of Alfvénic fluctuations from the outer corona to 1~AU…

Multi-spacecraft Measurements of the Evolving Geometry of the Solar Alfvén Surface Over Half a Solar Cycle

Samuel T. Badman, Michael L. Stevens, Stuart D. Bale +18

The geometry of a star's Alfvén surface determines stellar angular momentum loss, separates a causally distinct 'corona' and stellar wind, and potentially affects exoplanetary habi…

The Temperature Anisotropy and Helium Abundance Features of Alfvénic Slow Solar Wind Observed by Parker Solar Probe, Helios, and Wind Missions

Jia Huang, Davin E. Larson, Tamar Ervin +20

Slow solar wind is typically characterized as having low Alfvénicity, but the occasional occurrence of highly Alfvénic slow solar wind (HASSW) raises questions about its source reg…
