Modelling of the radiative transfer in the fine structures of the prominences represents a useful tool for understanding the quiescent prominences. A rather complex nature of the prominence fine structures requires sophisticated non-LTE radiative transfer computations coupled with advanced models of the prominence plasma. Therefore the main objectives of this project are the continuation of the development of complex prominence fine-structure models and the analysis of the observed prominence spectra. The work will be focused on three approaches to the development of the fine-structure models. The first is the study of asymmetries of observed Lyman profiles using the multi-thread prominence fine-structure models with line-of-sight velocities assigned randomly to each thread. The second approach is based on consistent hydrogen and helium radiative transfercomputations. The third represents the development of a 2.5D prominence/filament fine-structure model with coupled MHD relaxation and 3D radiative transfer computations. (en)
