• molecular cloud: HH objects: ejections: IR nebula

The results of investigation of molecular cloud LDN133 and the unstable objects HHL59, HHL59A, HHL59B and HHL59C connected with it are given. The IR nebula and IR star cluster are also connected with LDN133. It is shown that two different molecular outflows are present: (1) red-shifted molecular outflow from the IR nebula, connected with HHL59, and (2) bipolar molecular outflow from the object HHL59A. An IRAS point source IRAS 17554-2606 is connected with the IR nebula. Observations with narrow band filters revealed the existence of HH objects and jets from several unstable stars of this region. There are three filaments; ejected from the IR nebula with condensation at their ends. Two 8-type cometary nebulae connected with unstable stars were also discovered.
