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

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.

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 ...

Magnetic Connectivity in the Time-dependent Corona and Heliosphere

The Astrophysical Journal Letters
Magnetic flux fills the heliosphere, expands outward from the solar corona, and is fundamentally related to the structure and dynamics of the solar corona and solar wind.

Connecting Solar Orbiter and L1 Measurements of Mesoscale Solar Wind Structures to Their Coronal Source Using the ADAPT-WSA Model

The Astrophysical Journal
Much of the dynamics of the ambient solar wind (SW) manifests at mesoscales—scales larger than kinetic but smaller than global structures. Mesoscale structures often form at the Sun, survive to 1 au, and are geoeffective.
