Abstract

In a systematic search we looked for coincidences in the positions of eclipsing binaries and IRAS point sources as evidence of a physical association. In a detailed discussion of the available optical and infrared data combined with model calculations, we show that 50-75% of the coincidences between eclipsing binaries and IRAS sources are real. We discuss a subsample of 44 stars in some detail and surveyed the vicinity of them on POSS and SRC/ESO atlases for possible optical counterparts and present identification maps. In the cases of BS Sco and V 718 Sco the infrared radiation may come from an accretion disk.
