Aims of the project: The project is dealing with various physical and chemical processes occurring in atmospheres of exoplanets exposed to intense extreme ultraviolet radiation emitted by young stars located in the center of their planetary systems and plasmas created by high-velocity impacts of extraplanetary bodies and atmospheric electrical discharges of a different kind. The explorations will be performed using advanced facilities, devices, diagnostics and experimental layouts combined with the theory and computer simulations, chemical consequences of particular processes (e.g., shock, thermal and blast waves, non-thermal action of energetic photons and charged particles, fast quenching of the hot plasmas by ambient cold gas and surfaces of condensed matter, and so on) associated with the above-mentioned high-energydensity events in the atmospheres, especially that on young exoplanets. These results make it possible to achieve a more reliable interpretation of observation astronomy data, to simulate the transmission spectra and to estimate chemical conditions of prebiotic synthesis on young planets.
