Star-Forming Regions: Herbig-Haro Objects, Star-Forming Regions: Molecular Hydrogen

Scientific paper

The discovery of two jets and 18 HH-like objects in H2 (2.12 μm) emission in the star forming region NGC 7538 is reported. Strong H2 emission in a shell structure is observed to surround the northern IRS 1-3 nebula, and both the UV radiation field and outflow activity from the infrared sources could be responsible for the H2 emission. Morphologically, many of the H2 features are found to be consistent with enhanced molecular wind emission observed in the mm-waves. The results show that multiple outflows with very different directions are present in the three star forming regions, IRS 1-3, IRS 9 and IRS 11.
