Comparison of the Composition of the Tempel 1 Ejecta to the Dust in Comet C/Hale-Bopp 1995 O1 and YSO HD 100546
Abstract
Spitzer Infrared Spectrograph observations of the Deep Impact experiment in July 2005 have created a new paradigm for understanding the infrared spectroscopy of primitive solar nebular material -- the ejecta spectrum is the most detailed ever observed in cometary material. Here, we take the composition model for the material excavated from Comet 9P/Tempel 1's interior and successfully apply it to Infrared Space Observatory spectra of material emitted from Comet C/1995 O1 (Hale- Bopp) and the circumstellar material found around the young stellar object HD 100546. Comparison of our results with analyses of the cometary material returned by the Stardust spacecraft from Comet 81P/Wild 2, the in-situ Halley flyby measurements, and the Deep Impact data return provides a fundamental crosscheck for the spectral decomposition models presented here.
