TESIS on CORONAS-PHOTON S. V. Kuzin (XRAS) and TESIS Team

TESIS: scientific tasks www. tesis. lebedev. ru Scientific tasks: q Investigation of the most dynamic processes in the solar atmosphere, such as flares, coronal mass ejections, dimmings etc. q. Investigation of processes in far solar corona (up to 4 solar radii) in EUV q Study of evolution of large-scale long-life coronal structures: active regions, coronal loops, giant arcades, coronal holes and others. q. Determination of the physical parameters (electron temperature and density, differential emission measure) of plasma of coronal structures.

TESIS: targets of observations www. tesis. lebedev. ru Targets of observations: q Solar flares – their dynamics, energy balance and physical characteristics q Eruptive processes in the solar atmosphere – triggers and methods of forecasting q Coronal mass ejections – their formation and dynamics q Spectroscopy of coronal plasma in wide temperature range q Investigation of upper Earth atmosphere
