The investigation of quasi-separatrix layers in solar magnetic fields [PDF]
The structure of the magnetic field is often an important factor in many energetic processes in the solar corona. To determine the topology of the magnetic field features such as null points, separatrix surfaces, and separators must be found.

Topological structure of the magnetic solar corona [PDF]
The solar corona is a highly complex and active plasma environment, containing many exotic phenomena such as solar flares, coronal mass ejections, prominences, coronal loops, and bright points.

Relationship between plasma flow Doppler velocities and magnetic field parameters during the appearance of active regions at the solar photospheric level [PDF]
Using data obtained with the Michelson Doppler Imager (MDI) onboard the Solar and Heliospheric Observatory (SOHO), we have conducted a statistical study of the relationship between plasma flow Doppler velocities and magnetic field parameters during the appearance of active regions at the solar photospheric level.

Aims. Solar active regions (ARs) are key manifestations of the Sun’s magnetic activity, displaying diverse spatial and temporal characteristics. Their formation and evolution play a crucial role in understanding the solar dynamo and space weather. While individual ARs exhibit significant variability, ensemble averaging offers a method to extract their ...

Development and application of a global magnetic field evolution model for the solar corona [PDF]
Magnetic fields are fundamental to the structure and dynamics of the Sun’s corona. Observations show them to be locally complex, with highly sheared and twisted fields visible in solar filaments/prominences.

CME Velocity Field Calculation Model Based on an Unsupervised Transformer Optical Flow Network
The optical flow algorithm (OF) is one the main methods for calculating image velocity field and has many applications in space weather. Most OF calculations are applied to the motion of labeled rigid objects and are not suitable for velocity detection ...

Parallel and perpendicular cascades in solar wind turbulence [PDF]
MHD-scale fluctuations in the velocity, magnetic, and density fields of the solar wind are routinely observed. The evolution of these fluctuations, as they are transported radially outwards by the solar wind, is believed to involve both wave and ...
