The Astrophysical Journal Letters, 2023 We report direct observational evidence for a latitudinal dependence of dust cloud opacity in ultracool dwarfs, indicating that equatorial latitudes are cloudier than polar latitudes.

A Survey for New Members of Taurus with theSpitzer Space Telescope [PDF]
The Astrophysical Journal, 2006 We present the results of a search for new members of the Taurus star-forming region using the Infrared Array Camera (IRAC) aboard the Spitzer Space Telescope}. With IRAC images of 29.7 deg^2 of Taurus at 3.6, 4.5, 5.8, and 8.0 um, we have identified sources with red mid-infrared colors indicative of disk-bearing objects and have obtained optical and ...

Review of Spitzer Space Telescope observations of small bodies [PDF]
Proceedings of the International Astronomical Union, 2005 The Spitzer Space Telescope (SST), aloft for over two years at time of writing, has so far devoted almost 600 hours of observing time to Solar System science, and small bodies make up a significant fraction of the objects that have been observed. For the first time we now have high accuracy mid-infrared data to study the fundamental mineralogical and

Design of the Spitzer Space Telescope Heritage Archive [PDF]
, 2009 It is predicted that Spitzer Space Telescope’s cryogen will run out in April 2009, and the final reprocessing for the cryogenic mission is scheduled to end in April 2011, at which time the Spitzer archive will be transferred to the NASA/IPAC Infrared ...

Mid-Infrared Galaxy Morphology Along the Hubble Sequence
, 2004 The mid-infrared emission from 18 nearby galaxies imaged with the IRAC instrument on Spitzer Space Telescope samples the spatial distributions of the reddening-free stellar photospheric emission and the warm dust in the ISM.

Temporal Changes in the Infrared Spectra of Magellanic Carbon Stars
GalaxiesThe Medium-Resolution Spectrometer on the Mid-Infrared Instrument on the JWST obtained spectra of three carbon stars in the Large Magellanic Cloud. Two of the spectra differ significantly from spectra obtained ∼16–19 years earlier with the Infrared ...

Y Dwarf Trigonometric Parallaxes from the Spitzer Space Telescope [PDF]
The Astrophysical Journal, 2018 Abstract Y dwarfs provide a unique opportunity to study free-floating objects with masses <30 M Jup and atmospheric temperatures approaching those of known Jupiter-like exoplanets. Obtaining distances to these objects is an essential step toward characterizing their absolute physical properties.

The Planetary Science Journal, 2021 We have collected transit times for the TRAPPIST-1 system with the Spitzer Space Telescope over four years. We add to these ground-based, HST, and K2 transit-time measurements, and revisit an N -body dynamical analysis of the seven-planet system using ...
