Solar Spectropolarimetry

David Kuridze
Due to the high complexity of the solar atmosphere, advanced, high-resolution spectropolarimetric observations are required to investigate its thermodynamic properties including the characteristics of the magnetic field. High-resolution, full Stokes chromospheric spectropolarimetry from ground-based telescopes offers the opportunity to obtain such data sets. My research focus on design, execution, analysis and interpretation of ground-based spectropolarimetric observations. The main aim of my current projects are:
  1. Develop semi-empirical radiative hydrodynamic models of the chromospheric structures through advanced spectropolarimetric inversion techniques.
  2. Perform diagnostics of the key plasma parameters, such as temperature, density, plasma pressure, magnetic field and velocity.
  3. Study the spatial and temporal variation of the physical parameters in the chromospheric structures and their magnetohydrodynamic stability.
