Scientific paper

New high resolution echelle observations of Ofpe/WN9 stars in the Large Magellanic Cloud have been obtained in the wavelength region 4000 - 8000 Å. We find that five Ofpe/WN9 stars display in their spectra nebular emission lines [NII], [SII] and also [OIII], previously unreported for BE381 and S119. At least in these two cases we can conclude that the stars are surrounded by an associated nebula, thus strengthening the relationship between Ofpe/WN9 stars and LBVs.
