Impact of solar wind disappearance event on the Martian nightside ionospheric species: First results [PDF]

arXiv
The impact of a rarest solar wind phenomenon [disappearing solar wind (DSW) event during 26-28 December 2022] on the Martian nightside ionosphere is investigated, for the first time, using MAVEN datasets. During an extremely low solar wind density, the Martian top nightside ionospheric species underwent significant enhancements.

The Propagation and Evolution of Polar Cap Patches During Auroral Substorm Activity

Journal of Geophysical Research: Space Physics, Volume 130, Issue 5, May 2025.
Abstract Polar cap patches are islands of enhanced plasma density formed during intervals of southward interplanetary magnetic field (IMF). The present study examines the observations of polar cap patches during sequential auroral substorms that occurred on 9 September 2011.

New Models of Jupiter's Magnetopause and Bow Shock Through the Juno Prime Mission: Probabilistic Location, Shape, and Internally‐Driven Variation

Journal of Geophysical Research: Space Physics, Volume 130, Issue 5, May 2025.
Abstract The interaction between Jupiter's magnetosphere and the solar wind is not well‐constrained: while internal energetic plasma processes are thought to dominate plasma circulation, the solar wind nonetheless exerts significant control over the shape and scale of the whole structure.

Reconnection Onset in Overstretched Thin Current Sheets: PIC Simulations

Journal of Geophysical Research: Space Physics, Volume 130, Issue 5, May 2025.
Abstract Onset of reconnection in the magnetotail requires its current sheet (CS) to thin down to the thermal ion gyroradius (or thinner) to demagnetize ions (or even electrons) and to provide their Landau dissipation. However, in isotropic plasma models of the tail the ion‐scale CSs inflate too rapidly with the distance from Earth to remain ion‐scale ...

Coulomb collisions of ring current particles: Indirect source of heat for the ionosphere [PDF]

The additional energy requirements of the topside ionosphere during a magnetic storm are less than one quarter of the ring current energy. This energy is supplied largely by Coulomb collisions of ring current protons of energy less than about 20 keV with

Electron Acceleration and Zebra Stripe Formation in Saturn's Radiation Belts

Journal of Geophysical Research: Space Physics, Volume 130, Issue 5, May 2025.
Abstract This study uses the Versatile Electron Radiation Belt code to model Saturn's radiation belt environment, investigating electron acceleration, loss, and transport mechanisms. The simulations consider various physical processes, including convection particularly driven by a Volland‐Stern (VS) electric field, radial diffusion, collisional energy ...

A Method for the Ambient Equivalent Dose Estimation in a Wide Range of Altitudes during SEP and GLE Events

Atmosphere
The paper considers the modeling of proton transport through the Earth’s atmosphere during several SEP events (12 August 1989, 23 March 1991, and 8 November 2000), as well as during the GLE73 event.
