MMS data from a 2023 CME show elevated electron temperatures with superthermal tails, depleted mid-energy electrons, and weak MHD-like turbulence with reduced intermittency in the rare sub-Alfvénic solar wind at 1 AU.
Dual-spacecraft observations of a November 2021 CME confirm that the CAAP method reliably estimates instantaneous expansion speed from single-point data while revealing unexpected evolution in shock strength and magnetic flux.
CMEs during active solar phases are faster with stronger magnetic fields than in quiet phases (even after speed matching), while toroidal and poloidal field components decay similarly with distance and front-to-rear asymmetry increases.
Authors advocate precise terminology for interplanetary phenomena like CIRs over the broader SIR label and introduce Super CIR as a new category for exceptionally strong events from coronal hole jets.
This paper discusses observational, calibration, and imaging requirements for solar and heliospheric science with the SKA radio telescope.
