Abstract

The connection between the IRAS point sources catalog and following objects is studied: 1. H 2 O masers, 2. Herbig - Haro objects, 3. Cometary nebulae, 4. Compact nebulae, situated in the large nebulae, and 5. Dark globules. It is shown, that more than 50% of the 1, 2, 3, and 4 type objects are connected with the IRAS sources. More than 10 new H 2 O masers, connected with IRAS sources are found, one of them having very unusual properties. More than 10 dark globules are found in the Cep OB2 association, which are connected with IRAS sources. One of these sources consists of 4 components, forming a Trapezium-like configuration.
