Infrared spatial and spectral studies of an ionization front region in the Orion Nebula
Astronomy and Astrophysics EDP Sciences 76 (1979) 60-64-60-64
Abstract:
Spectrophotometric observations between 8 and 13 microns of an ionization-front region in Orion show that a large fraction of the radiation arises from the narrow unidentified emission features at 8.7 and 11.3 microns. This strongly featured continuum emission occurs throughout the length of the infrared bar. It is shown that the emission arises in a neutral region subjected to strong UV irradiation longward of the Lyman limit.10-MICRON Spectral Observations of Moderately Extended Planetary Nebulae
