The Second Quadratic Invariant of Astrophysical Gyrokinetics
Benjamin D. G. Chandran, Alfred Mallet, Romain Meyrand
The paper identifies a previously unknown quadratic invariant, called gyrokinetic helicity, in astrophysical gyrokinetics and derives its forms across several reduced plasma models…
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…
A Transport Theory of Turbulent Coronal Heating in General Geometry
Jonathan Squire, Benjamin D. G. Chandran, Toby Adkins +3
Magnetic geometry shapes how turbulence transports and dissipates energy in strongly magnetized plasmas. The solar corona, a maze of open and closed flux tubes with sharp transvers…
Cyclotron breaking: a mechanism for parallel ion cyclotron waves to heat the fast solar wind
Evan L. Yerger, Benjamin D. G. Chandran, Vincent David +2
The () mission has observed near-continuous power in parallel ion cyclotron waves (PICWs) in the young, fast solar wind. These waves are…
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…
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~A…
