Prysiazhnyi A. Physical conditions in the inhomogeneous magnetized photosphere of the Sun

The thesis is devoted to the diagnostics of physical conditions in a magnetized plasma of the solar atmosphere: in photospheric jets and in the surrounding atmosphere as well as within the facular region; to the study of the influence of magnetic field on convection, to the study of dynamics and evolution of long-lived elements of solar granulation. The work is based on observations, obtained with the VTT and SST telescopes (Canary Islands, Spain). 3D-models of the inhomogeneous photosphere of the Sun were built, including: jets and facular region; a model of photospheric region in which long-lived convective flows are present was built. The physical conditions inside and in the vicinity of photospheric jets and their dynamics are investigated. Centers of energy release are localized. For the first time on the basis of a new approach, the field of horizontal velocities in the vicinity of photospheric jets has been investigated. The influence of the magnetic field on convection is analyzed. The heights at which the process of mutual transformation of mechanical and internal energy of the photospheric plasma into the energy of the magnetic field takes place are determined. The dynamics and evolution of long-lived elements of solar granulation are investigated. The relationship between spatiotemporal variations of thermodynamic parameters and the process of granule fragmentation is analyzed.
