The first visible-light studies of Earth-sized extrasolar planets will employ photometry or low-resolution spectroscopy. This work uses EPOCh medium-band filter photometry between 350 and 950 nm…
CRYSTALLINE SILICATES IN EVOLVED STARS. I. SPITZER/INFRARED SPECTROGRAPH SPECTROSCOPY OF IRAS 16456−3542, 18354−0638, AND 23239+5754
We report the Spitzer Infrared Spectrograph (IRS) observations of three evolved stars: IRAS 16456−3542, 18354−0638, and 23239+5754. The 9.9–37.2 μm Spitzer/IRS high-resolution spectra of these three…
