Objects of study: Sun, magnetic fields in active regions in the Sun and its bowels, solar activity, aerosols in the Earth's atmosphere, climate change.
Purpose: To obtain more reliable and detailed data on small-scale magnetic fields and thermodynamic conditions in solar activity, such as solar flares, spots and flares. Refinement of the scenario of restructuring of strong toroidal fields in the bowels of the Sun and the impact of this restructuring on the observed manifestations of solar activity. Obtaining new data on the content of aerosols in the Earth's atmosphere and study the complex influence of aerosols and other climatic factors on the parameters of the Earth's climate system.
Research methods: spectral and spectropolarimetric, as well as methods of magnetohydrodynamics, theoretical physics and mathematical statistics.
Based on the solution of the multilevel polarization radiation transfer problem for the case of three-dimensional 3D solar MHD magneto-convection model, the reliability of Stokes-diagnostics methods of small-scale magnetic fields of the Sun in infrared Si I 1082.7 nm on modern (GRET, SST, etc.) DKIST, EST with 4 m diameter ground-based telescopes. Stokes-metric observations of the GST BBSO telescope in the Fel 15648.5 A infrared line were analyzed and the existence of two types of magnetic regions in the active region, including special areas with excessive magnetic fields with a strength of up to 5700 Hs, were established. Based on theoretical analysis of the latest data on magnetic fields in the Sun's interior, it is shown that a noticeable radial gradient of angular velocity in the radiating zone is sufficient to generate a powerful deep toroidal magnetic field of constant direction. New data on spectral optical thickness of aerosols in the air pool of Kiev within the activity of the international AERONET network were obtained and the volume concentration of aerosol particles, their size distribution, single scattering albedo, complex re
