The Stability of the Electron Strahl against the Oblique Fast-magnetosonic/Whistler Instability in the Inner Heliosphere
Seong-Yeop Jeong, Joel B. Abraham, Daniel Verscharen +8
We analyze the micro-kinetic stability of the electron strahl in the solar wind depending on heliocentric distance. The oblique fast-magnetosonic/whistler (FM/W) instability has em…
Test Problems for Potential Field Source Surface Extrapolations of Solar and Stellar Magnetic Fields
David Stansby, Daniel Verscharen
The potential field source surface (PFSS) equations are commonly used to model the coronal magnetic field of the Sun and other stars. As with any computational model, solving equat…
The Kinetic Expansion of Solar-Wind Electrons: Transport Theory and Predictions for the very Inner Heliosphere
Seong-Yeop Jeong, Daniel Verscharen, Christian Vocks +9
We propose a transport theory for the kinetic evolution of solar-wind electrons in the heliosphere. We derive a gyro-averaged kinetic transport equation that accounts for the spher…
Active region contributions to the solar wind over multiple solar cycles
D. Stansby, L. M. Green, L. van Driel-Gesztelyi +1
Both coronal holes and active regions are source regions of the solar wind. The distribution of these coronal structures across both space and time is well known, but it is unclear…
Alfvenic Perturbations in a Sunspot Chromosphere Linked to Fractionated Plasma in the Corona
D. Baker, M. Stangalini, G. Valori +7
In this study, we investigate the spatial distribution of highly varying plasma composition around one of the largest sunspots of solar cycle 24. Observations of the photosphere, c…
Enhanced proton parallel temperature inside patches of switchbacks in the inner heliosphere
L. D. Woodham, T. S. Horbury, L. Matteini +16
Switchbacks are discrete angular deflections in the solar wind magnetic field that have been observed throughout the heliosphere. Recent observations by Parker Solar Probe (PSP) ha…
