Abstract
New high resolution echelle observations of Ofpe/WN9 stars in the Larg e Magellanic Cloud have been obtained in the wavelength region 4000 - 8000 Angstrom. We find that five Ofpe/WN9 stars display in their spect ra nebular emission lines [NII], [SII] and also [OIII], previously unr eported for BE381 and S119. At least in these two cases we can conclud e that the stars are surrounded by an associated nebula, thus strength ening the relationship between Ofpe/WN9 stars and LBVs.
