| Popis: | Observational data on an active star formation region in the dense molecular cloud Orion KL in the form of H2O maser emission are analyzed in terms of a hydrodynamic whirlwind mechanism for the excitation of bipolar outflows from the disk system. The whirlwind theory for the excitation of bipolar flows from the disk system is found to provide a first order approximation for explaining the major observed features of the active region and the structure accompanying the formation of a protostar: a disk-bipolar flow, including the mechanism by which it is ejected and autocollimated, and the excitation of maser radiation. |
