Topside Reconnection

Frontiers in Physics, 2020
It is proposed that reconnection would be a main mechanism governing the plasma processes on auroral time scales in the topside ionosphere/high-latitude magnetosphere transition.

The low acute effectiveness of a high-power short duration radiofrequency current application technique in pulmonary vein isolation for atrial fibrillation

Cardiology Journal, 2021
BACKGROUND: Application of high power radiofrequency (RF) energy for a short duration (HPSD) to isolate pulmonary vein (PV) is an emerging technique. But power and duration settings are very different across different centers.

Effect of interchange instability on magnetic reconnection [PDF]

Nonlinear Processes in Geophysics, 2013
We present here the results of a study of interacting magnetic fields that involves a force normal to the reconnection layer. In the presence of such force, the reconnection layer becomes unstable to interchange disturbances.

Eruption and Interplanetary Evolution of a Stealthy Streamer-Blowout CME Observed by PSP at ∼0.5 AU

Frontiers in Astronomy and Space Sciences, 2022
Streamer-blowout coronal mass ejections (SBO-CMEs) are the dominant CME population during solar minimum. Although they are typically slow and lack clear low-coronal signatures, they can cause geomagnetic storms.

The reversibility of magnetic reconnection [PDF]

Physics of Plasmas, 2021
The reversibility of the transfer of energy from the magnetic field to the surrounding plasma during magnetic reconnection is examined. Trajectories of test particles in an analytic field model demonstrate that irreversibility is associated with separatrix crossings and passages through regions of weaker magnetic field.

Kelvin-Helmholtz Instability Associated With Reconnection and Ultra Low Frequency Waves at the Ground: A Case Study

Frontiers in Physics, 2021
The Kelvin-Helmholtz instability (KHI) and its effects relating to the transfer of energy and mass from the solar wind into the magnetosphere remain an important focus of magnetospheric physics.

Magnetohydrodynamic Turbulence in the Earth’s Magnetotail From Observations and Global MHD Simulations

Frontiers in Astronomy and Space Sciences, 2021
Magnetohydrodynamic (MHD) turbulent flows are found in the solar wind, the magnetosheath and the magnetotail plasma sheet. In this paper, we review both observational and theoretical evidence for turbulent flow in the magnetotail.

Is Our Understanding of Solar-Wind/Magnetosphere Coupling Satisfactory?

Frontiers in Astronomy and Space Sciences, 2021
An assessment of our physics-based understanding of solar-wind/magnetosphere coupling finds that the understanding is not complete. Solar-wind/magnetosphere coupling is foundational to magnetospheric physics and it is a key to comprehending and ...

La dette écologique en questions : propos introductifs

VertigO, 2016
This paper enlights the concept of ecological debt through the diversity of its definitions and consequences. What is the “power” of the concept ? What are the objects (material and immaterial debt) and its consequences ?

Ion‐scale structure in Mercury's magnetopause reconnection diffusion region

Geophysical Research Letters, 2016
The strength and time dependence of the electric field in a magnetopause diffusion region relate to the rate of magnetic reconnection between the solar wind and a planetary magnetic field.
