We present long-slit 10 um spectra of HD 44179. The object is resolved in the unidentified infrared features at 7.7, 8.6, and 11.3 µm. Another feature at 12.8 µm, which may be related to the unidentified infrared features or may be [Ne II], is similarly resolved. The source of the smooth underlying continuum is only marginally resolved by the present observations and analysis. These results demonstrate the power of long-slit spectra in revealing spatial structures via their spectral signature.
This paper was chapter 3 of Sloan's dissertation, and represents the preliminary analysis of long-slit spectra of the Red Rectangle prior to developing techniques for maximum entropy reconstruction of long-slit spectra. The concept of the spatiogram, a plot of the width of a source as a function of wavelength, is introduced here.
