The Ofpe/WN9 class in the Large Magellanic Cloud

Description

The remarkable Ofpe/WN9 spectoscopic category in the LMC now contains ten members, including two newly identified here. Both photographic and digital spectrograms are presented, to establish the characteristics of the class in terms of the latter data, as a reference for future work. Two of these objects have shown large spectrum variations which transiently remove them from the class; one is currently undergoing a giant outburst which establishes it a as Luminous Blue Variable and suggests the possibility that the others may also be quiescent LBVs. Some significant correlations with the recent infrared spectral phenomenology of McGregor et al. (1988) are also pointed out.
