    Diagnostics of the dynamics of the Langmuir spectrum based on radio emission during the 12 March 2015 solar radio burst

  • Original language description

    We investigate the dynamics of spectra of Langmuir waves in the plasma radiation of solar radio bursts. We simulated the radio emission that is formed during the merging of Langmuir waves. The observed frequency spectra of radio bursts were fitted by the model spectrum of Langmuir waves. We determined shapes of the Langmuir wave spectra, consistent with the solar burst observed in the 0.8-2.0 GHz range on 12 March 2015 by the Ondrejov radiospectrograph. We estimated the sizes of the corresponding radio source for different values of the energy density of Langmuir waves. We present the time evolution of the model Langmuir wave spectra at four instants. Finally, we explain a role of the induced scattering of Langmuir waves in the formation of their spectra.
