Physics

Scientific paper

Because X-ray emission traces stellar magnetic activity, samples of pre-main sequence stars identified through X-ray emission are unbiased in terms of the presence of circumstellar disks. Using the Chandra X-ray Observatory, we have obtained a large sample of this kind for intermediate and solar-mass stars (0.4-8 solar masses) in the Cepheus B star-forming region. To measure the frequency of circumstellar disks as a function of mass in this cluster, and thus fully exploit the unbiased nature of our Chandra sample, we propose to obtain mid-IR photometry of these stars with the Infrared Array Camera aboard the Spitzer Space Telescope.
