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

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

The paper presents a new method to directly measure velocity‑space diffusion coefficients from Parker Solar Probe data, using these measurements to evaluate stochastic versus reson…

On the Radial Evolution of the Solar Wind : The Source Alignment Method Applied to Parker Solar Probe and Solar Orbiter Observations

Jean-Baptiste Dakeyo, Tamar Ervin, Stuart Bale +10

The properties of the solar wind, as measured in situ throughout the heliosphere, depend both on the characteristics of its coronal source and on the intrinsic processes governing…

Perpendicular ion heating in turbulence and reconnection: magnetic moment breaking by coherent fluctuations

Alfred Mallet, Kristopher G. Klein, Benjamin D. G. Chandran +2

We study the interaction of an ion with a fluctuation in the electromagnetic fields that is localized in both space and time. We study the scale-dependence of the interaction in bo…

On the Relation between Source Region and In-situ Variability of Low Solar Wind Streams

Kai Jaffarove, Tamar Ervin, Stuart D. Bale

Parker Solar Probe (PSP) observed a high speed stream near the Sun () in March 2025. As this stream was observed near the Sun, it allowed for an unparalleled oppo…

Proton specific entropy as a proxy for the charge state ratio over heliocentric distance

Jack D. Collard, Tamar Ervin, Ryan M. Dewey +10

While the fast solar wind has well-established origins in coronal holes, the source of the slow solar wind remains uncertain. Compositional metrics, such as heavy ion charge state…

In situ Evidence of 5-minute Oscillations from Parker Solar Probe

Zesen Huang, Marco Velli, Olga Panasenco +19

The Sun's surface vibrates in characteristic 5-minute oscillations, known as p-modes, generated by sound waves trapped within the convection zone. Although these oscillations have…
