Current sheets in planetary magnetospheres [PDF]

Plasma Physics and Controlled Fusion, 2019
Abstract In this article we aim to highlight the problems related to the structure and stability of the comparatively thin current sheets that were relatively recently discovered by space missions in the magnetospheres of the Earth and planets, as well as in the solar wind. These magnetoplasma structures are universal in collisionless

A Simplified Ordinary Differential Equation for the Surface Temperature of Airless Bodies

Earth and Space Science
In this work, we develop simplified surface temperature models for spherical bodies with insignificant atmospheres, able to produce a latitude/longitude temperature map that includes seasonality effects.

X-rays Studies of the Solar System [PDF]

, 2019
X-ray observatories contribute fundamental advances in Solar System studies by probing Sun-object interactions, developing planet and satellite surface composition maps, probing global magnetospheric dynamics, and tracking astrochemical reactions ...

Stellar wind-magnetosphere interaction at exoplanets: computations of auroral radio powers

, 2016
We present calculations of the auroral radio powers expected from exoplanets with magnetospheres driven by an Earth-like magnetospheric interaction with the solar wind.

Observational signatures of the giant planets collisions

, 2013
We consider observational signatures of the collisions and partial destructions of giant exoplanets at the chaotic stage of the planetary systems evolution. The rate of these collisions in the Galaxy is estimated to be ~0.01-1 per yr.

Magnetospheric considerations for solar system ice state [PDF]

, 2018
The current lattice configuration of the water ice on the surfaces of the inner satellites of Jupiter and Saturn is likely shaped by many factors. But laboratory experiments have found that energetic proton irradiation can cause a transition in the ...

Hall Fields and Current Systems of Magnetic Reconnection under Asymmetric Conditions

The Astrophysical Journal, 2023
The Hall effect is a key component of collisionless reconnection. A previous study showed that a quadrupolar Hall pattern under symmetric conditions degenerates into a bipolar pattern under highly asymmetric conditions.

The magnetic fields of forming solar-like stars

, 2010
Magnetic fields play a crucial role at all stages of the formation of low mass stars and planetary systems. In the final stages, in particular, they control the kinematics of in-falling gas from circumstellar discs, and the launching and collimation of ...

Hall Effect in the coma of 67P/Churyumov-Gerasimenko [PDF]

, 2018
Magnetohydrodynamics simulations have been carried out in studying the solar wind and cometary plasma interactions for decades. Various plasma boundaries have been simulated and compared well with observations for comet 1P/Halley.

Global Wind Field Reconstruction in the Mesosphere and Lower Thermosphere (MLT) During Geomagnetic Storms by Fusing TIDI and SABER Data: A Generative Adversarial Network (GAN) Approach

Geoscience Data Journal, Volume 13, Issue 3, July 2026.
ABSTRACT The Mesosphere and Lower Thermosphere establish an essential connection between Earth's lower atmosphere and upper atmosphere because wind patterns essential for atmospheric movement also influence energy distribution and chemical movements during geomagnetic storms that disrupt satellite operations and space weather prediction systems.
