Star-forming processes in Cepheus OB2

The properties of IRAS point sources in the region of the “Cepheus bubble” were studied. This bubble is a possible very old supernova remnant which includes the association Cepheus OB2. A large number of sources which are probably low- and medium-mass embedded stars are situated around the bubble. It is concluded that whereas high-mass stars which have formed in the bubble are already on the main sequence, lower-mass stars are still embedded in their parent clouds.
