Evidence for Magnetic Reconnection at Ganymede's Upstream Magnetopause During the PJ34 Juno Flyby

Geophysical Research Letters, 2022
Juno made a close flyby of Ganymede and flew through its magnetosphere on 7 June 2021, including an outbound crossing of Ganymede's upstream magnetopause. We present plasma and magnetic field observations near the upstream magnetopause from Juno's Jovian

Juno Magnetometer Observations at Ganymede: Comparisons With a Global Hybrid Simulation and Indications of Magnetopause Reconnection

Geophysical Research Letters, 2022
Juno's flyby of Ganymede on 7 June 2021, provides a unique opportunity to explore the moon's magnetosphere. By means of Magnetometer (MAG) observations and a hybrid numerical simulation, we provide a global description of this environment and analyze the

Interplanetary Shock‐Induced Magnetopause Motion: Comparison Between Theory and Global Magnetohydrodynamic Simulations [PDF]

Geophysical Research Letters, 2021
The magnetopause marks the outer edge of the Earth's magnetosphere and a distinct boundary between solar wind and magnetospheric plasma populations. In this study, we use global magnetohydrodynamic simulations to examine the response of the terrestrial ...

Do Statistical Models Capture the Dynamics of the Magnetopause During Sudden Magnetospheric Compressions? [PDF]

Journal of Geophysical Research: Space Physics, 2020
Under periods of strong solar wind driving, the magnetopause can become compressed, playing a significant role in draining electrons from the outer radiation belt.

MMS Examination of FTEs at the Earth's Subsolar Magnetopause [PDF]

, 2018
Determining the magnetic field structure, electric currents, and plasma distributions within flux transfer event (FTE)‐type flux ropes is critical to the understanding of their origin, evolution, and dynamics. Here the Magnetospheric Multiscale mission's

Bursty magnetic reconnection at the Earth's magnetopause triggered by high-speed jets [PDF]

Physics of Plasmas, 2021
The impact of high-speed jets -- dynamic pressure enhancements in the magnetosheath -- on the Earth's magnetopause has been observed to trigger local magnetic reconnection.

Magnetopause Reconnection and Indents Induced by Foreshock Turbulence [PDF]

Geophysical Research Letters, 2021
Based on global hybrid simulation results, we predict that foreshock turbulence can reach the magnetopause and lead to reconnection as well as Earth‐sized indents. Both the interplanetary magnetic field (IMF) and solar wind are constant in our simulation,

Energetic particle loss through the magnetopause: A combined global MHD and test‐particle study

, 2017
We study the spatiotemporal characteristics of energetic particle losses from the magnetosphere using test‐particle trajectories in electromagnetic fields from a global magnetosphere magnetohydrodynamic (MHD) simulation.

Resolving Magnetopause Shadowing Using Multimission Measurements of Phase Space Density

Journal of Geophysical Research - Space Physics, 2022
Loss mechanisms act independently or in unison to drive rapid loss of electrons in the radiation belts. Electrons may be lost by precipitation into the Earth's atmosphere, or through the magnetopause into interplanetary space—a process known as ...
