Magnetic Field Variability as a Consistent Predictor of Solar Flares

The Astrophysical Journal
Solar flares are intense bursts of electromagnetic radiation that occur due to a rapid destabilization and reconnection of the magnetic field. While preflare signatures and trends have been investigated from magnetic observations prior to flares for ...

Analysis of CME Interactions in Solar Corona Combining Coronagraphic Observations with Wide-field Imagers from Solar Orbiter and Parker Solar Probe

The Astrophysical Journal
Accurately determining the trajectory of coronal mass ejections (CMEs) is vital for space weather forecasting and assessing their potential impact on Earth. CMEs often deviate from a radial path, due to local pressure gradients or interactions with other

Solar origins of solar wind properties during the cycle 23 solar minimum and rising phase of cycle 24

Journal of Advanced Research, 2013
The solar wind was originally envisioned using a simple dipolar corona/polar coronal hole sources picture, but modern observations and models, together with the recent unusual solar cycle minimum, have demonstrated the limitations of this picture.

The Temperature and Emission Measure Distribution in the Quiet and Active Solar Corona: A Bayesian Approach

The Astrophysical Journal, 2022
Abstract The reconstruction of the differential emission measure (DEM) from observations of spectral line intensities provides information on the temperature distribution of the emission measure in the region observed. The inversion process is known to be highly unstable, and it has been necessary to provide additional constraints, such ...

Energy Transport and Heating by Nonthermal Electrons in a Turbulent Solar Flare Environment

The Astrophysical Journal
The impulsive phase of a solar flare is known to generate strong turbulence and to transfer magnetic energy into accelerated electrons. Recognizing the importance of angular diffusion on the dynamics of the accelerated electrons, we extend previous ...

Challenges in Forecasting the Evolution of a Distorted CME Observed During the First Close Solar Orbiter Perihelion

The Astrophysical Journal
Coronal Mass Ejections (CMEs), drivers of the most severe Space Weather disturbances, are often assumed to evolve self-similarly during their propagation.

SuNeRF: 3D Reconstruction of the Solar EUV Corona Using Neural Radiance Fields

The Astrophysical Journal Letters
To understand its evolution and the effects of its eruptive events, the Sun is permanently monitored by multiple satellite missions. The optically thin emission of the solar plasma and the limited number of viewpoints make it challenging to reconstruct ...
