Radio emissions from sun spots

27 August 2010

At www.physorg.com/print201972151.html … professor Jeongwoo Lee (see also www.csun.edu/physicsandastronomy/IAUS273/) seeks to explain why sun spots are a source of radio emissions because hot electrons gyrate in the coronal magnetic field. As they gyrate they produce an efficient radiation called gyro-resonant emission. This serves as an indicator of the magnetic field and of temperature in the coronae above sun spots.
