Scientific paper

We propose a joint Chandra/ACIS and Spitzer/IRS survey of plasma and thermal dust emission from CI Cam and five other galactic B[e] supergiant systems that are bright mid-IR sources. The results will test the hypothesis that many such stars harbor quiescent, "CI Cam-like" X-ray sources, and that these sources may be intimately related to the presence of binary companions as well as to the dusty disks recently detected in IRS spectoscopy of B[e] supergiants. ACIS spectrscopy will establish the presence and strength of any Fe fluorescence line emission in these systems. In parallel, the proposed joint Spitzer IRS observations will provide the means to ascertain the origin and evolution of dusty disks around B[e] supergiants.
