Title: Identifying B[e] Supergiants in the Magellanic Clouds from Photometry

Abstract: The late stages of evolution of massive stars are poorly understood, and they deserve further study. One such class of massive star is the B[e] supergiant. Precious few B[e]SGs have been identified to date. We ask for Gemini-South GMOS spectroscopy of 30 B[e] supergiant candidates, that we have newly identified via optical/IR photometry, in order to confirm their identities as B[e] supergiants. A previous NOAO program of ours chose 4 targets as B[e] supergiant candidates based on their optical/IR photometry, and 3 were found to be B[e] supergiants, demonstrating the usefulness of this approach.
