Spatially Resolved Spectra of the Red Rectangle in the N-Band

We have observed the Red Rectangle by our newly developed instrument COMICS attached on the SUBARU 8.2 m telescope, and obtained images and spectra in the N-band (8–13.2µm). Diffraction limited spatial resolution (~ 0.35 arcsec) was almost achieved, revealing differences of dust emission profiles with its distance from the central star. In the nebula region (distance > 260 AU), UIR emissions at 7.7, 8.6, 11.27, and 12.7 µm were prominent, while spectra around the central star (distance < 260 AU) are dominated by strong continuum emissions.
