On the fluctuations of electron density and magnetic field in the solar mid-corona: spacecraft radio observations

, 2020
Context: The mechanisms for solar wind acceleration remain speculative despite decades of research. Magnetohydrodynamic (MHD) wave energy is believed to play a key role in powering the solar wind, but characterization of the magnetic energy transport ...

The Solar Corona

Abstract The solar corona is the hot, tenuous outer layer of the Sun’s atmosphere. The coronal plasma is roughly around 1 mega-Kelvin (MK) but can reach temperatures of around 10 MK in certain regions. Due to this high temperature, the plasma in the corona emits electromagnetic radiation predominantly at Extreme Ultraviolet (EUV) and ...

Observations of Circularly Polarized Radio Emission from the “Quiet” Sun at Frequencies <100 MHz

The Astrophysical Journal
The presence of the magnetic field makes the solar coronal medium birefringent. Research indicates that an appreciable degree of circular polarization (DCP) can be observed in the thermal radio emission at frequencies

New Insights into Type-I Solar Noise Storms from High Angular Resolution Spectroscopic Imaging with the Upgraded Giant Metrewave Radio Telescope

The Astrophysical Journal
Type-I solar noise storms are perhaps the most commonly observed active radio emissions from the Sun at meter-wavelengths. Noise storms have a long-lived and wideband continuum background with superposed islands of much brighter narrowband and short ...

Observationally quantified reconnection providing a viable mechanism for active region coronal heating

Nature Communications, 2018
The solar corona heating mechanism is still subject to debate. Here, the authors report that impulsive reconnection can give rise to an active region corona that is compatible with extreme-ultraviolet observations.
