We have undertaken a search for SAO stars with infrared excess in the IRAS Point Source Catalog. In contrast to previous searches, the entire IRAS -- colour-colour diagram was used. This selection yielded a sample of 462 stars, of which a significant number are stars with circumstellar material. The stars selected can be identified as Pre-Main-Sequence stars, Be stars, Proto-Planetary Systems, Post-AGB stars, etc. A number of objects are (visual) binary stars. Characteristic temperatures and IR excesses are calculated and their relations to spectral type are investigated.
