Les spectres a faible resolution de geantes froides et supergeantes observes par l'IUE contiennent des structures d'emission pour lesquelles il est difficile d'obtenir des identifications sans ambiguites. Les spectres a haute resolution de RR Tel et β Gru montrent des raies pouvant etre attribuees a Fe II. Confirmation en laboratoire
