The ionization structure of the Orion Nebula.
Abstract
New long-slit spectra and existing CCD imagery were used to examine the ionization structure and develop a new picture of the central 5' of M42. The basic picture is of a highly ionized cavity surrounding the Trapezium, a low ionization zone to the southwest of θ1Ori C, and a region of high ionization further to the southwest where the molecular cloud curves back toward the observer. A bar-like feature to the northeast of the Trapezium and a Herbig Haro object to the west are also discussed.
