Dense cores in dark clouds. V - CO outflow

摘要: Sixteen dense cores in nearby clouds having low-mass stars have been surveyed the J = 1-0 line of C-12O at 2.6 mm with 14-m Five College Radio Astronomy Observatory telescope Massachusetts. Results suggest that CO outflows occur more than half star-core systems and typical outflow lasts most life system. The are shown to be characterized by frequent incidence, long duration, significantly great momentum kinetic energy. These results indicate traced may main agent dispersal cores. Outflows would thus play an important role determining main-sequence mass stars. 53 references.
