Derivation of the major properties of prominences using NLTE modelling

I introduce techniques to derive the major properties of prominences based on NLTE modelling. The main results of one- and two-dimensional models of the prominences and their fine-structures are presented. Modelling the radiative transfer processes out of local thermodynamic equilibrium allows one to retrieve the prominence plasma parameters (temperature, density, pressure, ionisation degree) as well as the prominence’s mass
