Scientific paper

The Infrared Spectrograph on the Spitzer Space Telescope was used for observations of the Kepler supernova remnant, with all four instrument modules targeted on the bright infrared knot located at 17h30m35.80s, -21d28m54.0s (J2000). The low spectral resolution modules' data show a dust continuum spectrum consistent with dust grains heated by high-energy electrons, while the high resolution modules' data show atomic emission line ratios consistent with excitation by a high velocity shock of >100 km/sec and electron densities of 1,000/cm. The abundance ratios for the six detected elements show signs of heavy-element enhancement.
This work is based on observations made with the Spitzer Space Telescope, which is operated by the Jet Propulsion Laboratory, California Institute of Technology under NASA contract 1407. Support for this work was provided by NASA's Office of Space Science.
