Scientific paper

Plate material concerning 34 Be stars in the 8309-8791-A region was obtained at the Observatoire de Haute Provence at 33 A/mm dispersion. It is found that emissions are frequent in all Be stars, but are more concentrated in early-type stars. The same phenomenon is found for the Ca II emissions, where a positive correlation of Ca II emission and large IR excesses measured with the IRAS satellite is demonstrated.
