Reflection Nebulae: Molecular Hydrogen
Scientific paper
Images have been obtained of the (fluorescent) molecular hydrogen 1 - 0 S(1) line, and of the 3.3 μm emission feature, in Orion's Bar and three reflection nebulae. The emission from these species appears to come from the same spatial locations in all sources observed. This suggests that the 3.3 μm feature is excited by the same energetic UV-photons which cause the molecular hydrogen to fluoresce.
