The Orion Nebula in the Far-Infrared: FIFI-LS/SOFIA Mapped the PDR
Abstract
The Orion Nebula is the closest massive star forming region allowing us to study the physical conditions in such a region with high spatial resolution. We used the far infrared integral-field spectrometer, FIFI-LS, on-board the airborne observatory SOFIA to study the atomic and molecular gas in the Orion Nebula at medium spectral resolution. The large maps in several fine structure lines obtained with FIFI-LS cover the nebula from the BN/KL-object in the west to the bar in the south-east and gull feature in north-east. The fine structure lines can be used as a diagnostic for the physical conditions of the photon-dominated region (PDR), the interface between the HII-region and the molecular cloud.
