Sunward flow in Jupiter's magnetosheath
Geophysical Research Letters, 1980 The position of Voyager crossings of Jupiter's bow shock show a dependence on solar wind pressure to the −1/3 power. This dependence is used to calculate typical bow shock speeds of 50 km/s from Voyager solar wind plasma data. Since the bow shock and magnetopause move approximately in unison in response to solar wind pressure changes, the resulting ...

Classifying Magnetosheath Jets using MMS - Statistical Properties [PDF]
Journal of Geophysical Research: Space Physics, 2019 Abstract Using Magnetospheric Multiscale (MMS) data, we find, classify, and analyze transient dynamic pressure enhancements in the magnetosheath (jets) from May 2015 to May 2019. A classification algorithm is presented, using in situ MMS data to classify jets ( ) into ...

Unveiling the 3D Structure of Magnetosheath Jets
Monthly Notices of the Royal Astronomical Society, 2023 Magnetosheath jets represent localized enhancements in dynamic pressure observed within the magnetosheath. These energetic entities, carrying excess energy and momentum, can impact the magnetopause and disrupt the magnetosphere. Therefore, they play a vital role in coupling the solar wind and terrestrial magnetosphere. However, our understanding of the

Multiple Reconnection X‐Lines at the Earth's Magnetopause in the Presence of Magnetosheath Flow
Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract Magnetic reconnection occurs continuously along long X‐lines at the Earth's magnetopause. The maximum magnetic shear model predicts the locations of these long X‐lines for a wide range of upstream solar wind conditions. One of the more perplexing observational results is that these X‐lines appear to be stationary, even in the presence of ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract Short Large‐Amplitude Magnetic Structures (SLAMS) are believed to play important roles in the physics governing the formation of quasi‐parallel shocks. These isolated non‐linear structures, frequently observed in the foreshock, have been suggested to be building blocks for the shock and have been shown to drive shock reformation. In this work,

Magnetic clouds' structure in the magnetosheath as observed by Cluster and Geotail: four case studies [PDF]
Annales Geophysicae, 2014 Magnetic clouds (MCs) are large-scale magnetic flux ropes ejected from the Sun into the interplanetary space. They play a central role in solar–terrestrial relations as they can efficiently drive magnetic activity in the near-Earth environment.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract We apply a hybrid model (kinetic ions, fluid electrons) to provide context for MErcury Surface Space ENvironment, GEochemistry, and Ranging (MESSENGER) observations of Disappearing Dayside Magnetosphere (DDM) events at Mercury. Such events have been observed on four occasions and are caused by Coronal Mass Ejections completely removing the ...

A multi-spacecraft survey of magnetic field line draping in the dayside magnetosheath [PDF]
Annales Geophysicae, 2005 When the interplanetary magnetic field (IMF) encounters the Earth's magnetosphere, it is compressed and distorted. This distortion is known as draping, and plays an important role in the interaction between the IMF and the geomagnetic field.

Space Weather, Volume 24, Issue 3, March 2026.Abstract A simulation of the 10 May 2024 geomagnetic storm is used to investigate the theory of cross polar cap potential (CPCP) saturation in Earth's magnetosphere‐ionosphere system. THEMIS B (ARTEMIS P1) satellite magnetic field and plasma measurements at lunar distance upstream in the solar wind drives the Space Weather Modeling Framework (SWMF) in ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract The magnetic Prandtl number in the slow solar wind is estimated by using magnetic and velocity Reynolds numbers. The Prandtl number quantifies the ratio of kinetic to magnetic diffusion rates in a plasma, and indicates which process dominates the transport dynamics in a fluid.
