Resolving the very fine details of the Sun in low frequency radio

Radio images of the Sun taken by a range of radio observatories at different frequencies.

The Sun is an active radio emitter, it produces radio emissions in a wide frequency range from kHz to THz. The solar atmosphere has a complex distribution of magnetic field, plasma density, and temperature. These different properties of the solar atmosphere will result in different radio emission features at different frequencies. In principle, the plasma density decreases with the heliocentric di ...[Read More]
