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…
Parker Solar Probe Observations of Compound Reconnection Exhaust Boundaries and Mirror-Mode Structures in the Near-Sun Heliospheric Current Sheet
Weijie Sun, Tai Phan, Jia Huang +12
Magnetic reconnection is a fundamental physical process that can drive rapid conversion of magnetic energy into plasma bulk flows, thermal heating, and particle acceleration in spa…
On the magnetic field evolution of interplanetary coronal mass ejections from 0.07 to 5.4 au
Christian Möstl, Emma E. Davies, Eva Weiler +8
A central question for understanding interplanetary coronal mass ejection (ICME) physics and improving space weather forecasting is how ICMEs evolve in interplanetary space. We hav…
Ion-Scale Solitary Structures in the Solar Wind Observed by Solar Orbiter and Parker Solar Probe
Yufei Yang, Timothy S. Horbury, Domenico Trotta +12
We investigate a class of ion-scale magnetic solitary structures in the solar wind, characterized by distinct magnetic field enhancements and bipolar rotations over spatial scales…
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…
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 hab…
