Solar Radio Emission

The sun is a radio active star sitting 'relatively-near' to us, which gave us the chance to observe the radio emission at very high resolution (compared to other stars).

Low Frequency Quiet Sun

With the Low Frequency Array LOFAR, we can observe the radio emission at low frequency (20-80 MHz) of the quiet sun. With LOFAR core+remote stations, integral 2.45 hours during a quiet pierod time of the Sun, we produced the high fidelity image of the quiet Sun.

Also we can derive the temperature spectrum of the quiet Sun, indicating lower than modeled thermal bremsstrahlung emission spectrum, detailed in the paper. QuietSunTb
