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…
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…
The Incompressible Magnetohydrodynamic Energy Cascade Rate Upstream of Mars: Effects of the Total Energy and the Cross-Helicity on Solar Wind Turbulence
Norberto Romanelli, Nahuel Andres, Gina DiBraccio +5
Solar wind turbulence is a dynamical phenomenon that evolves with heliocentric distance. Orbiting Mars since September 2014, Mars Atmosphere and Volatile EvolutioN (MAVEN) offers a…
Resonance of low-frequency electromagnetic and ion-sound modes in the solar wind
I. Y. Vasko, F. S. Mozer, T. Bowen +6
Parker Solar Probe measurements have recently shown that coherent fast magnetosonic and Alfvén ion-cyclotron waves are abundant in the solar wind and can be accompanied by higher-f…
Alfvén Waves at Mars
Norberto Romanelli, Christopher M. Fowler, Gina A. DiBraccio +2
The solar wind upstream of Mars's bow shock can be described in terms of Alfvénic turbulence, with an incompressible energy cascade rate of J m s at magnet…
Quantifying the Energy Budget in the Solar Wind from 13.3-100 Solar Radii
J. S. Halekas, S. D. Bale, M. Berthomier +10
A variety of energy sources, ranging from dynamic processes like magnetic reconnection and waves to quasi-steady terms like the plasma pressure, may contribute to the acceleration…
Proton and electron temperatures in the solar wind and their correlations with the solar wind speed
Chen Shi, Marco Velli, Roberto Lionello +8
The heating and acceleration of the solar wind remains one of the fundamental unsolved problems in heliophysics. It is usually observed that the proton temperature is highly…
The Radial Evolution of the Solar Wind as Organized by Electron Distribution Parameters
J. S. Halekas, P. Whittlesey, D. E. Larson +9
We utilize observations from the Parker Solar Probe (PSP) to study the radial evolution of the solar wind in the inner heliosphere. We analyze electron velocity distribution functi…
Statistical Analysis of the Radial Evolution of the Solar Winds between 0.1 and 1 au, and their Semi-empirical Iso-poly Fluid Modeling
Dakeyo, Maksimovic, Démoulin +2
Statistical classification of the Helios solar wind observations into several populations sorted by bulk speed has revealed an outward acceleration of the wind. The faster the wind…
Machine Learning Solar Wind Driving Magnetospheric Convection in Tail Lobes
Xin Cao, Jasper S. Halekas, Stein Haaland +2
To quantitatively study the driving mechanisms of magnetospheric convection in the magnetotail lobes on a global scale, we utilize data from the ARTEMIS spacecraft in the deep tail…
Parker Solar Probe evidence for the absence of whistlers close to the Sun to scatter strahl and regulate heat flux
C. Cattell, A. Breneman, J. Dombeck +14
Using the Parker Solar Probe FIELDS bandpass filter data and SWEAP electron data from Encounters 1 through 9, we show statistical properties of narrowband whistlers from ~16 Rs to…
A solar source of Alfvénic magnetic field switchbacks: {\em in situ} remnants of magnetic funnels on supergranulation scales
S. D. Bale, T. S. Horbury, M. Velli +17
One of the striking observations from the Parker Solar Probe (PSP) spacecraft is the prevalence in the inner heliosphere of large amplitude, Alfvénic magnetic field reversals terme…
Characteristic scales of magnetic switchback patches near the Sun and their possible association with solar supergranulation and granulation
Naïs Fargette, Benoit Lavraud, Alexis Rouillard +16
Parker Solar Probe (PSP) data recorded within a heliocentric radial distance of 0.3 AU have revealed a magnetic field dominated by Alfvénic structures that undergo large local vari…
Ambipolar electric field and potential in the solar wind estimated from electron velocity distribution functions
Laura Bercic, Milan Maksimovic, Jasper S. Halekas +17
The solar wind escapes from the solar corona and is accelerated, over a short distance, to its terminal velocity. The energy balance associated with this acceleration remains poorl…
Electron heat flux in the near-Sun environment
J. S. Halekas, P. L. Whittlesey, D. E. Larson +15
We survey the electron heat flux observed by the Parker Solar Probe (PSP) in the near-Sun environment at heliocentric distances of 0.125-0.25 AU. We utilized measurements from the…
Inner-Heliosphere Signatures of Ion-Scale Dissipation and Nonlinear Interaction
Trevor A. Bowen, Alfred Mallet, Stuart D. Bale +19
We perform a statistical study of the turbulent power spectrum at inertial and kinetic scales observed during the first perihelion encounter of Parker Solar Probe. We find that oft…
Relating streamer flows to density and magnetic structures at the Parker Solar Probe
Alexis P. Rouillard, Athanasios Kouloumvakos, Angelos Vourlidas +34
