Information × Registration Number 0115U002094, ( 0220U100579  ) R & D request Title Studies of the structure and dynamics of magnetic structures on the Sun Head Shchukina Nataliya G., Registration Date 28-01-2015 Organization Main Astronomical Observatory popup.description1 The study of small-scale magnetic fields of the quiet Sun. Investigation of wave processes in the magnetic structures of the quiet and active Sun (flares, spots, matter emissions, prominences, etc.). Study of the magnetized chromospheric plasma and the mechanisms that cause heating of the chromosphere and higher layers. Investigation of processes of reconnection (re-coupling) of magnetic force lines in solar plasma. Finding out the influence of three-dimensional and magnetic effects on determining the chemical composition of the Sun. Calculation of a new set of three-dimensional (3D) models of magnetic convection including not only the photosphere, but also higher layers above the temperature minimum. Numerical modeling of Stokes profiles of solar spectral lines for realistic models of atoms (so-called multilevel models) and for dynamic inhomogeneous models of the solar atmosphere. Carrying out long-term ground-based observations of Stokes I-profiles of Fraunhofer lines with high spectral resolution. popup.nrat_date 2024-12-10 Close
