Scientific paper

This paper presents the results of a search for CO outflows in a dark cloud complex near IC 5146 carried out using the 45-m telescope at Nobeyama Radio Observatory (HPBW = 17'') equipped with the S115Q multi-beam receiver system. A CO outflow was discovered by the present survey toward IRAS 21428+4732, whose physical parameters, such as molecular mass, mechanical momentum, and kinetic energy, were derived. In addition to IRAS 21428+4732, there are 5 other IRAS point sources accompanied by CO outflows in this cloud complex, which were found by earlier observations with lower angular resolutions (HPBW ~= 1'). We also made 12CO(J=1-0), 13CO(J=1-0), and C18O(J=1-0) observations toward the 5 sources with the 45-m telescope in order to obtain new data with higher angular resolutions. CO maps as well as physical parameters of these outflows obtained by the 45-m telescope are also presented.
