Is Our Understanding of Solar-Wind/Magnetosphere Coupling Satisfactory?

open access: yesFrontiers in Astronomy and Space Sciences, 2021
An assessment of our physics-based understanding of solar-wind/magnetosphere coupling finds that the understanding is not complete. Solar-wind/magnetosphere coupling is foundational to magnetospheric physics and it is a key to comprehending and ...

Insights on the Sun Birth Environment in the Context of Star Cluster Formation in Hub–Filament Systems

open access: yesThe Astrophysical Journal Letters, 2023
Cylindrical molecular filaments are observed to be the main sites of Sunlike star formation, while massive stars form in dense hubs at the junction of multiple filaments.

Scaling and a Fokker-Planck model for fluctuations in geomagnetic indices and comparison with solar wind as seen by Wind and ACE [PDF]

open access: yes, 2005
The evolution of magnetospheric indices on temporal scales shorter than that of substorms is characterized by bursty, intermittent events that may arise from turbulence intrinsic to the magnetosphere or that may reflect solar wind-magnetosphere coupling.
