The star formation structure and H2O supermaser radiation in Orion KL

The extra fine structure of the active region of H2O supermaser emission of Orion KL ( angular resolution is 0.1 mas) is studied. A central body / accretion disk / bipolar outflow / bullets / envelope is discovered, that corresponds to the earliest stage of the small-mass star formation. The ejector - a compact bright source less than or equal to 0.05 AU, T-b approximate to 10(17)K. The bipolar outflow, v(ej) approximate to 10 km/s is a highly-collimated stream with a ration length/diameter similar to 60, rotation period is similar to 0.5 yr, precession period similar to 10 yrs, precession angle similar to 33degrees. Precession forms a conical helix jet. The envelope amplified radio emission by about three orders of magnitude at velocity at v=7.65 km/s.
