Mid-infrared spectra of Comet Tempel 1 during the DI event

Mid-infrared spectra of Comet Tempel 1 during the DI event. In the left column MICHELLE spectra show the evolution of the silicate feature during the impact event. The middle panels show acquisition images of the comet at each epoch. The right column summarized modeling of the silicate feature. In the models, the colored lines denote different minerals. The different components add to fit the observed feature.
