Context. Time-resolved observations of loops embedded in the solar corona show the existence of motions of matter inside these structures, as well as the global motions of these objects themselves. Aims. We have developed a modeling tool for cylindri

One of the most enigmatic regions of the solar atmosphere is the transition region (TR), corresponding to plasmas with temperatures intermediate of the cool, few thousand K, chromosphere and the hot, few million K, corona. The traditional view is tha

Context. Relatively cool and dense structures embedded in the solar corona (filaments, prominences, spicules, etc.) may be observed in hydrogen lines. Sometimes they last during several solar rotations. Aims. Our goal is to evaluate the lifetime of c

We aim at studying the effect of radial motions on the spectrum emitted by moving prominences in the helium resonance lines and at facilitating the interpretation of observations, in order to improve our understanding of these dynamic structures. We

A numerical code is proposed for the solution of NLTE radiative transfer equations in long cylinders, including multilevel atoms and anisotropic incident radiation (which implies a 2-dimension treatment of the radiation field). It is applied to the m

This is a review of methods for the solution of non-LTE radiative transfer equations in long cylinders. The principal goal of these methods is the modelling of elongated structures imbedded in the solar corona, such as loops or prominence threads. Th

In this work we use new results of radiative transfer calculations out of local thermodynamical equilibrium to study the triplet lines emitted by neutral helium in solar quiescent prominences. We compare two types of prominence atmospheres: isotherma
