X-ray emitting B stars in the Great Carina Nebula: curiosity or new paradigm?

Normally B-type stars are relatively X-ray quiet. However, the recent deep, systematic X-ray imaging survey of the Great Carina Nebula, CCCP using Chandra, has now shown that a significant fraction of its B stars are strong X-ray emitters often with a hard component. This implies the presence of young, late-type, X-ray active companions or magnetic activity in the B star itself. We will attempt to determine which of these scenarios is the more likely by obtaining repeated spectra using GMOS at Gemini/South.
