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…

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…

Statistical Energy Budget of the Solar Wind with Parker Solar Probe and Solar Orbiter : 1 - Unbalanced Total Energy Radial Evolution

Jean-Baptiste Dakeyo, Pascal Démoulin, Victor Réville +9

The magneto-hydrodynamic (MHD) description of the solar wind has long been regarded as one of the most successful frameworks for investigating solar wind heating and acceleration.…

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…

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…

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…

Stochastic Heating in the Sub-Alfvénic Solar Wind

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

Collisionless dissipation of turbulence is important for heating plasmas in astrophysical, space physics, and laboratory environments, controlling energy, momentum and particle tra…

Differentiating the acceleration mechanisms in the slow and Alfvénic slow solar wind

Yeimy J. Rivera, Samuel T. Badman, J. L. Verniero +18

In the corona, plasma is accelerated to hundreds of kilometers per second, and heated to temperatures hundreds of times hotter than the Sun's surface, before it escapes to form the…

Mixed Source Region Signatures Inside Magnetic Switchback Patches Inferred by Heavy Ion Diagnostics

Yeimy J. Rivera, Samuel T. Badman, Michael L. Stevens +13

Since Parker Solar Probe's (Parker's) first perihelion pass at the Sun, large amplitude Alfvén waves grouped in patches have been observed near the Sun throughout the mission. Seve…

Characteristics and Source Regions of Slow Alfvenic Solar Wind Observed by Parker Solar Probe

Tamar Ervin, Kai Jaffarove, Samuel T. Badman +3

Using a classification scheme for solar wind type based on the heliocentric distance of the observation, we look at near perihelion observations from Parker Solar Probe Encounters…

Near subsonic solar wind outflow from an active region

Tamar Ervin, Stuart D. Bale, Samuel T. Badman +10

During Parker Solar Probe (Parker) Encounter 15 (E15), we observe an 18-hour period of near subsonic ( 1) and sub-Alfvénic (SA), <<< 1, slow speed…

Compositional metrics of fast and slow Alfvenic solar wind emerging from coronal holes and their boundaries

Tamar Ervin, Stuart D. Bale, Samuel T. Badman +7

We seek to understand the composition and variability of fast (FSW) and slow Alfvenic solar wind (SASW) emerging from coronal holes (CH). We leverage an opportune conjunction betwe…
