Investigating the Occurrence of Magnetic Reconnection at Jupiter's Dawn Magnetopause During the Juno Era

Geophysical Research Letters, 2022
In this study, observations from the Jovian auroral distributions experiment, Jupiter energetic particle detector instrument, and Magnetic field investigation instruments on Juno are used to identify signatures of magnetic reconnection at Jupiter's dawn ...

Excitation of field line resonances by sources outside the magnetosphere [PDF]

Annales Geophysicae, 2005
Field line resonances are thought to be excited by sources either at the magnetopause or outside it. Recent observations suggest that they may be associated with coherent oscillations or pressure pulses in the solar wind. In either case the excitation

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

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 ...

Prediction of Axial Asymmetry in Jovian Magnetopause Reconnection

Geophysical Research Letters, 2023
We show the possible existence of a significant axial asymmetry in the reconnection separator at the Jovian magnetopause using first‐principle, physics‐based global simulations. Under eastward interplanetary magnetic field (IMF) conditions near Jupiter's

Magnetopause energy and mass transfer: results from a global MHD simulation [PDF]

Annales Geophysicae, 2006
We use the global MHD model GUMICS-4 to investigate the energy and mass transfer through the magnetopause and towards the closed magnetic field as a response to the interplanetary magnetic field (IMF) clock angle θ=arctan (BY/BZ), IMF magnitude ...

A linear perturbation analysis of magnetopause motion in the Newton-Busemann limit [PDF]

Annales Geophysicae, 1995
The response of the magnetopause surface to time-varying solar wind dynamic pressure is examined. We argue that to a first approximation the magnetopause surface may be considered as analogous to an elastic membrane. Upon displacement from equilibrium

The azimuthal extent of three flux transfer events [PDF]

Annales Geophysicae, 2008
In early 2006, the Cluster spacecraft crossed the dayside magnetopause twice each orbit with the spacecraft at their largest separation of the entire mission (~10 000 km).

Surface waves on the dawn and dusk flanks of Jupiter’s magnetopause

Astronomy & Astrophysics
Context. The Jovian magnetopause is a highly dynamic boundary that experiences substantial deformation driven by interactions with the co-rotating internal plasma and the solar wind, leading to the development and propagation of wave activity along the ...

Possible configurations of the magnetic field in the outer magnetosphere during geomagnetic polarity reversals [PDF]

Annales Geophysicae, 2000
Possible configurations of the magnetic field in the outer magnetosphere during geomagnetic polarity reversals are investigated by considering the idealized problem of a magnetic multipole of order m and degree n located at the centre of a spherical ...

The Shape of Strongly Disturbed Dayside Magnetopause

Terrestrial, Atmospheric and Oceanic Sciences, 2013
During strong geomagnetic disturbances, the Earth¡¦s magnetosphere exhibits unusual and nonlinear interaction with the incident flow of magnetized solar wind plasma. Global Magneto-hydro-dynamic (MHD) modeling of the magnetosphere predicts that the storm-
