Photospheric Kelvin--Helmholtz Vortices as Possible Drivers of Coronal Heating: Implications of the DKIST Observations
Katariina Nykyri
The Daniel K. Inouye Solar Telescope (DKIST) has resolved Kelvin--Helmholtz (KH) vortices at photospheric magnetic-flux boundaries with a characteristic wavelength of 65 km. I esti…
Relativistic Scaling and Magnetization-Current Feedback in Stern Gerlach-Modified Pair-Plasma Reconnection: SpinPIC2D Validation and Nonlinear Regimes
K. Nykyri
We investigate the relativistic scaling and electromagnetic feedback of Stern--Gerlach (SG) force driven spin transport in pair-plasma reconnection with SpinPIC2D. The model advanc…
Stern--Gerlach Spin Sorting and Dynamical Feedback in Relativistic Pair-Plasma Reconnection
K. Nykyri
We derive a Stern--Gerlach control parameter, , comparing spin-driven cross-sheet displacement with the relativistic Larmor radius. It places heliospheric plasmas and most astro…
Observation of Large-Scale Kelvin-Helmholtz Instability Wave Driven by a Coronal Mass Ejection
Leon Ofman, Olga Khabarova, Ryun-Yong Kwon +3
The Kelvin-Helmholtz instability (KHI) can occur when there is a relative motion between two adjacent fluids. In the case of magnetized plasma, the shear velocity must exceed the l…
Editorial: Impacts of the Extreme Gannon Geomagnetic Storm of May 2024 throughout the Magnetosphere-Ionosphere-Thermosphere System
Denny M. Oliveira, Mirko Piersanti, Maria-Theresia Walach +4
Editorial for the Research Topic collection Impacts of the Extreme Gannon Geomagnetic Storm of May 2024 throughout the Magnetosphere-Ionosphere-Thermosphere System, published in Fr…
Unveiling plasma energization and energy transport in the Earth Magnetospheric System: the need for future coordinated multiscale observations
A. Retino, L. Kepko, H. Kucharek +31
Energetic plasma is everywhere in the Universe. The terrestrial Magnetospheric System is a key case where direct measures of plasma energization and energy transport can be made in…
Reimagining Heliophysics: A bold new vision for the next decade and beyond
Ian J. Cohen, Dan Baker, Jacob Bortnik +25
The field of Heliophysics has a branding problem. We need an answer to the question: ``What is Heliophysics\?'', the answer to which should clearly and succinctly defines our scien…
Defining the Middle Corona
Matthew J. West, Daniel B. Seaton, David B. Wexler +31
The middle corona, the region roughly spanning heliocentric altitudes from to , encompasses almost all of the influential physical transitions and processes that…
Magnetospheric Multi-Scale Observations of High-Energy Electrons and Protons in the Vicinity of Southern High-Altitude Cusp Boundaries
Katariina Nykyri, Christina Chu, Xuanye Ma +1
Recent Magnetosphere Multiscale (MMS) observations found 238 high energy (> 40 keV) electron "leaking" events in the the magnetosheath [Cohen et al., 2017]. While several sources h…
