In recent years, the Spitzer Space telescope observed thermal emission spectra of two hot Jupiter exoplanets, HD189733b and HD209458b, at wavelengths from 5 to approximately 14 microns. Those spectra were acquired using the IRS instrument, at a spectral resolving power of approximately 100. We report progress on a re-analysis of all the Spitzer IRS data for both planets, including some data not previously published. Our analysis exploits the recently improved understanding of instrument and detector effects, such as using a double-exponential function to account for the ramp effect at the longest wavelengths. There is much recent interest in future exoplanet spectroscopy using JWST, and our work is aimed at improving extant methodology for transit and eclipse
spectroscopy of extrasolar planets in the thermal infrared.
