On the properties of single-separator MHS equilibria and the nature of separator reconnection [PDF]

, 2015
This thesis considers the properties of MHS equilibria formed through non-resistive MHD relaxation of analytical non-potential magnetic field models, which contain two null points connected by a generic separator. Four types of analytical magnetic fields

Recent advances in magnetic reconnection in Mars’ space environment

Discover Space
Magnetic reconnection has recently emerged as an important process in the Martian space environment. In contrast to Earth, Mars lacks a global intrinsic dipole field and possesses an induced magnetosphere shaped by solar-wind interaction with the ...

Formation and motion of a transpolar arc in response to dayside and nightside reconnection [PDF]

, 2005
We trace the formation and subsequent motion of a transpolar arc in response to dayside and nightside reconnection. Both high- and low-latitude dayside reconnection are observed, as well as periods of substorm and nonsubstorm nightside reconnection ...

Direct Observations of Magnetic Reconnections at the Magnetopause of the Martian Mini‐Magnetosphere

Geophysical Research Letters
While Mars lacks a global intrinsic magnetic field, it does exhibit crustal magnetic anomalies (mostly in its Southern Hemisphere). These crustal magnetic anomalies directly interact with solar wind, which forms a mini‐magnetosphere and a region denoted ...

The Observations of Magnetic Reconnection during the Interaction Process of Two Active Region Filaments

The Astrophysical Journal
We investigate the interaction between two filaments (F1 and F2) and their subsequent magnetic reconnection in active region (AR) NOAA 13296 and AR NOAA 13293 on 2023 May 9, utilizing high spatial and temporal resolution and multiwavelength observational

Solar Magnetic Activity and Its Terrestrial Impact through Correlations with Drought Indices

Physical Sciences and Technology
Solar activity manifests itself in the form of sunspots on the solar surface and solar flares, which can influence Earth's climatic conditions, including drought in mid-latitude regions.

Connecting Solar Wind Velocity Spikes Measured by Solar Orbiter and Coronal Brightenings Observed by SDO

The Astrophysical Journal Letters
The Parker Solar Probe's discovery that magnetic switchbacks and velocity spikes in the young solar wind are abundant has prompted intensive research into their origin(s) and formation mechanism(s) in the solar atmosphere.

From Photospheric Footpoint Motion to Plasmoid Ejection: A Two-stage Reconnection Process in a Small-scale Chromospheric Jet

The Astrophysical Journal Letters
Using high-spatiotemporal-resolution multiwavelength observations from the New Vacuum Solar Telescope and the Solar Dynamics Observatory, we present a detailed analysis of a small-scale chromospheric jet driven by plasmoid-mediated magnetic reconnection.
