IMAGING STUDIES OF LOCALIZED, IONIZED FLOWS IN THE ROSETTE NEBULA

Optical ([S II] 6717 & 6731 Angstrom, [S III] 9069 Angstrom, [O III] 5 007 Angstrom and H alpha + [N II] 6584 Angstrom), K-band, H-2 1-0 S(1) 2.122 mu m and [Fe II] 1.64 mu m imagery has been obtained of a group of high-speed knots close to the core of the Rosette nebula. A high-s peed, high-excitation, bow-shaped structure has been directly imaged i n [O III] 5007 Angstrom for the first time and is interpreted as a bow shock either at the head of a collimated flow or around a fast-moving molecular bullet. Two candidates for the driving source of these moti ons have also been identified in a system where no sources were previo usly known.
