| Abstract: |
We present high resolution Spitzer spectroscopy of several pointings in the outflow of the Red Rectangle. Besides the resonances due to the C-rich PAHs, the spectra show a wealth of new emission bands, in particular in the 13–19.5 μm range. We argue that these bands are due to solid state components, and show that simple oxides of a varying composition show a good match to the data. The presence of these O-rich species in the supposedly C-rich outflow is unexplained. |
