Flare Star A member of a class of stars that show occasional, sudden, unpredicted increases in light. The total energy released in a flare on a flare star can be much greater that the energy released in a solar flare . The intersection of magnetic loops with the photosphere . An electron that has broken free of it's atomic bond and is therefore not bound to an atom. The higher the frequency, the greater the energy of the radiation and the smaller the wavelength .
Frequency is measured in Hertz .
Gamma rays are often defined to begin at 10 keV , although radiation from around 10 keV to several hundred keV is also referred to as hard x-rays . A worldwide disturbance of the Earth's magnetic field , associated with solar activity. Hertz Abbreviated Hz . A unit of frequency equal to one cycle per second. Hydromagnetic Wave A wave in which both the plasma and magnetic field oscillate.
