Fe II emission lines in Be stars : I. Empirical diagnostic of physical conditions in the circumstellar discs

Aims. The Fe II emission lines formed in the circumstellar envelopes (CE) of classical Be stars are studied in order to determine whether they are optically thin or optically thick. We also aim at deriving both average Fe II line excitation temperatures and the extent of their formation region in th...
