Comparative Study on Planetary Magnetosphere in the Solar System [PDF]

Sensors, 2020
The magnetospheric responses to solar wind of Mercury, Earth, Jupiter and Uranus are compared via magnetohydrodynamic (MHD) simulations. The tilt angle of each planetary field and the polarity of solar wind are also considered.

Nonlinear spatiotemporal signatures of whistler-mode wave activity around Mercury during six flybys of BepiColombo mission [PDF]

Nature Communications
Cyclotron resonance between electromagnetic waves and plasmas may be a universal acceleration phenomenon of charged particles in magnetized planets. Coherent fine structures of whistler-mode waves serve as a signature of nonlinear resonance. However, the

The origins of patchy aurora at Jupiter [PDF]

Nature Communications
Auroral emissions play a critical role in coupling the magnetosphere and atmosphere at magnetized planets. At Jupiter, isolated auroral patches equatorward of the main auroral oval have been associated with magnetospheric injections, yet the key ...

Global-scale magnetosphere convection driven by dayside magnetic reconnection [PDF]

Nature Communications
Plasma convection on a global scale is a fundamental feature of planetary magnetosphere. The Dungey cycle explains that steady-state convection within the closed part of the magnetosphere relies on magnetic reconnection in the nightside magnetospheric ...

Closed magnetic topology in the Venusian magnetotail and ion escape at Venus [PDF]

Nature Communications
Venus, lacking an intrinsic global dipole magnetic field, serves as a textbook example of an induced magnetosphere, formed by interplanetary magnetic fields (IMF) enveloping the planet.

Open Magnetic Fields in the Martian Magnetosphere Revealing Dipole-like Intrinsic Magnetic Fields at Mars

The Astrophysical Journal Letters, 2023
Mars’s magnetosphere is hybrid, having contributions from both an induced magnetosphere like Venus and the localized crustal magnetic fields. However, the planetary fields also include large-scale, more global components.

Comparing Jupiter and Saturn: dimensionless input rates from plasma sources within the magnetosphere [PDF]

Annales Geophysicae, 2008
The quantitative significance for a planetary magnetosphere of plasma sources associated with a moon of the planet can be assessed only by expressing the plasma mass input rate in dimensionless form, as the ratio of the actual mass input to some ...

Plasma Imaging, LOcal Measurement, and Tomographic Experiment (PILOT): A Mission Concept for Transformational Multi-Scale Observations of Mass and Energy Flow Dynamics in Earth’s Magnetosphere

Frontiers in Astronomy and Space Sciences, 2022
We currently do not understand the fundamental physical processes that govern mass and energy flow through the Earth’s magnetosphere. Knowledge of these processes is critical to understanding the mass loss rate of Earth’s atmosphere, as well as for ...

A quantitative model of the planetary Na⁺ contribution to Mercury’s magnetosphere [PDF]

Annales Geophysicae, 2003
We examine the circulation of heavy ions of planetary origin within Mercury’s magnetosphere. Using single particle trajectory calculations, we focus on the dynamics of sodium ions, one of the main species that are ejected from the planet’s ...

Sliding Contacts in Planetary Magnetospheres [PDF]

Symmetry, 2021
In the planetary magnetospheres there are specific places connected with velocity breakdown, reconnection, and dynamo processes. Here we pay attention to sliding layers. Sliding layers are formed in the ionosphere, on separatrix surfaces, at the magnetopauses and boundaries of stellar astrospheres, and at the Alfvén radius in the equatorial ...
