A Possible Indication of the Insufficiency of Simplistic Homogeneous Models for Estimating Magnetic Fields of CMEs using Gyrosynchrotron Emission by Devojyoti Kansabanik et al.

2024-11-19

Coronal mass ejections (CMEs) are large-scale plasma and magnetic field expulsions from the solar corona into the heliosphere. The magnetic field entrained in the CME plasma is crucial to understanding their propagation, evolution, and geo-effectiveness. Among the different observables at radio wavelengths, spectral modeling of faint gyrosynchrotron (GS) emission from CME plasma has been regarded as one of the most promising remote observing techniques for estimating spatially resolved CME magnetic […]

Observations of coronal holes with the Siberian Radio Heliograph by Altyntsev et al.

2024-11-05

Coronal holes (CHs) are regions of reduced brightness in solar disk images in extreme ultraviolet (EUV) or soft X-ray emissions corresponding to configurations with open magnetic field lines. Data on their area and depth of brightness depression is used in forecasts of solar wind parameters in the vicinity of Earth. Regular two-dimensional observations of CHs in microwaves with a spatial resolution to 10–20“ began in the 1990s at frequencies of […]
