Abstract

We present a study of the X-ray emission coming from B-type stars in binary systems. The sample has been extracted from the Lindroos catalogue (Lindroos, 1986) and consists of six visual pairs comprised of a B-type star and a later-type companion. Surprisingly, we have detected X-ray emission coming from the late-B primaries, suggesting the presence of a third unresolved late-type star or an unknown mechanism which generates X-rays in late-B stars.
