Review of Machine Learning Models for Solar Energetic Particle Prediction
Spiridon Kasapis, Pouya Hosseinzadeh, Kathryn Whitman +73
Solar energetic particle (SEP) events have attracted increasing attention due to their significant radiation hazards for aviation, spacecraft electronics, and human missions beyond…
Modeling of AR 12760 with GX Simulator and Evidence for the Extended Transition Region in Peripheral Active Region Loops
Therese A. Kucera, Gelu M. Nita, James A. Klimchuk +1
In order to understand solar atmospheric heating it is important to test heating models against spatially resolved data from solar active regions. Here we model a small active regi…
First Detailed MeerKAT Imaging Spectroscopy of a Solar Flare
Yingjie Luo, Eduard P. Kontar, Roelf Du Toit Strauss +5
Radio observations provide powerful diagnostics of energy release, particle acceleration, and transport processes in solar flares. However, despite recent progress in radio interfe…
MeV-peaked electrons in a coronal source of a solar flare
Gregory D. Fleishman, Ivan Oparin, Gelu M. Nita +3
Analysis of γ-rays in solar flares has suggested a distinct continuum component dominating at MeV energies, which differs from the well-studied X-ray continuum produced by flare-a…
Magneto-Thermal Coupling and Coronal Heating in Solar Active Regions Inferred from Microwave Observations
Alexey A. Kuznetsov, Gregory D. Fleishman, Gelu M. Nita +1
The solar corona is much hotter than the photosphere and chromosphere, but the physical mechanism responsible for heating the coronal plasma remains unidentified yet. The thermal m…
Steady-State Heating of Diffuse Coronal Plasma in a Solar Active Region
Gregory D. Fleishman, Alexey A. Kuznetsov, Gelu M. Nita
Solar corona is much hotter than lower layers of the solar atmosphere-photosphere and chromosphere. The coronal temperature is up to 1MK in quiet sun areas, while up to several MK…
