Subject and Achievement of Past Research
Research topics and achievements are mostly based on spectrometric and radioheliograph observations. Among them are:
– Discovery of the dynamic mm-wavelength spectral flattening during the decay phase of solar radio bursts indicating on strong trapping of mildly relativistic electrons in flaring loops (Melnikov and Magun. Sol.Phys.1998);
– discovery of phase delays in ms-pulsation decimeter radio bursts and development of new diagnostic tools for flaring loop’s plasma (Fleishman, Fu, Huang, Melnikov, Astr. & Astrophys. 2002; Melnikov, Fleishman, Fu, Huang, Astr.Rep. 2002);
– discovery of a new class of optically thin microwave flaring loops characterized by the peak of their brightness located in the loop top (Melnikov, Shibasaki and Reznikova. ApJ 2002);
– discovery of the enhanced concentration of relativistic electrons with the anisotropic pitch-angle distribution in the upper part of microwave flaring loops. These discoveries put important new constraints on the location of the acceleration site in a flaring loop and on particle acceleration/injection mechanisms in solar flares (Melnikov et al. ApJ 2002, Melnikov et al. BRAS (Phys) 2006);
– theoretical prediction and subsequent discovery of the effect of the mildly relativistic electrons’ pitch-angle anisotropy on the spectrum and polarization of gyrosynchrotron emission (Fleishman and Melnikov. ApJ 2003). The discovery of this effect provide us with new powerful tools for the diagnostics of acceleration processes in solar flares;
– theoretical solution of the non-stationary kinetic Fokker-Plank equation which describes the dynamics of non-thermal electrons’ spatial, energy and pitch angle distributions in flare magnetic loops under various electron injection functions (Melnikov et al. BRAS (Phys) 2006, Gorbikov and Melnikov. Math.Model. 2007);
– development of new independent tools for the diagnostics of plasma density and magnetic field in flaring loops based on studies of MHD waves in magnetic wave-guides: observational proof of the existence of the global sausage mode in flaring loops (Nakariakov, Melnikov, Reznikova 2003); discovery of a spatial structure of periodic modulation of microwave emission in flaring loops (Melnikov et al. 2005); theoretical prediction of the microwave detectability of slow acoustic modes in flaring loops by the modulation of Razin suppression (Nakariakov and Melnikov, 2006).
