... The morphology of the emissionnebula can provide observational constraints for the predictions of the common envelope mass loss and the nebular emission can be used to place constraints on the initial mass of the system. ...
... This was one of our motivations in obtaining high-resolution images of H 2 emission in the Orion Bar with NICMOS. ... The Orion Bar is the visible ionization boundary of the Orion Nebula, southeast of the Trapezium. ...
... Based on the annular appearance of the emission lines (which are, effectively, monochromatic images of the nebula), the nebula itself is spatially resolved, while a spatially unresolved continuum from the central star is also seen. ...
... the right shows the intrinsic spectrum of the planetary nebula formed by subtracting the restored background image (top right ... Weak emission lines, such as [O III]4363A, are detectable. Hook, R.N., Lucy. L.B., Stockton, A. Ridgway, S., 1994. ...

... Figure 15: A sketch of the region close to the Kleinmann-Low nebula is shown. ... The shaded region in the NE to SW direction is the Ridge component, which is a part of very extended emission. ...
