Magnetic Field, Electron Density and Their Spatial Scales in Zebra Pattern Radio Sources

Popis výsledku v původním jazyce

Zebra patterns (zebras) play an important role in the plasma diagnostics during solar flares. Considering their double plasma resonance (DPR) model, we present an improved method for the determination of the gyro-harmonic numbers of the zebra stripes that are essential in determining the electron density and magnetic field strength in zebra sources. Furthermore, we present the magnetic field and density spatial scales in zebra sources. Compared to the previous method, we change the basic assumption of the method. Namely, the assumption that the ratioR=L-bh/L-nh (L-bh and L-nh are the magnetic field and density scales) is constant in the whole zebra source is changed to its more generalized form, where the ratio R is a linear function. Using this improved method, first, we determine the gyro-harmonic numbers of several observed zebras and variations of the spatial scales.
