radioheli

Radioheli is a term that can refer to a few related concepts in radio astronomy and the study of the Sun. At its core, it relates to the observation of radio waves emitted by the Sun. This can encompass the study of the Sun's atmosphere, particularly the corona, and the various phenomena occurring there, such as solar flares and coronal mass ejections.

Instruments specifically designed for this purpose are sometimes called radioheliographs. These are arrays of radio telescopes that work together to create images of the Sun at radio wavelengths. By observing the Sun across different radio frequencies, astronomers can probe different layers of its atmosphere and study the behavior of charged particles and magnetic fields. These observations provide crucial information about the Sun's activity, which can have an impact on Earth, a field known as space weather.

The study of radioheli phenomena helps scientists understand the complex processes driving solar activity. Analyzing the radio emissions allows for the detection and characterization of energetic events. This contributes to our broader understanding of stellar physics and the Sun's influence on the solar system.
