A Spitzer/IRAC Census of the Asymptotic Giant Branch Populations in Local Group Dwarfs. I. WLM
Dale C. Jackson, Evan D. Skillman, Robert D. Gehrz +2
We present Spitzer/IRAC observations at 3.6 and 4.5 microns along with optical data from the Local Group Galaxies Survey to investigate the evolved stellar population of the Local…
The Spitzer IRS view of V4334 Sgr (Sakurai's Object)
A. Evans, V. H. Tyne, J. Th. van Loon +11
We present an observation of the very late thermal pulse object V4334 Sgr (Sakurai's Object) with the Infrared Spectrometer (IRS) on the Spitzer Space Telescope. The emission from…
A Spitzer Study of Comets 2P/Encke, 67P/Churyumov-Gerasimenko, and C/2001 HT50 (LINEAR-NEAT)
Michael S. Kelley, Charles E. Woodward, David E. Harker +8
We present infrared images and spectra of comets 2P/Encke, 67P/Churyumov-Gerasimenko, and C/2001 HT50 (LINEAR-NEAT) as part of a larger program to observe comets inside of 5 AU fro…
Spitzer Space Telescope Infrared Imaging and Spectroscopy of the Crab Nebula
Tea Temim, Robert D. Gehrz, Charles E. Woodward +7
We present 3.6, 4.5, 5.8, 8.0, 24, and 70 micron images of the Crab Nebula obtained with the Spitzer Space Telescope IRAC and MIPS cameras, Low- and High-resolution Spitzer IRS spe…
Hot Dust and PAH Emission at Low Metallicity: A Spitzer Survey of Local Group and Other Nearby Dwarf Galaxies
Dale C. Jackson, John M. Cannon, Evan D. Skillman +4
We present Spitzer Space Telescope 4.5 and 8.0 micron imaging of 15 Local Group and nearby dwarf galaxies. Our sample spans a range of more than one dex in nebular metallicity and…
M33's Variable A -- A Hypergiant Star More Than 35 Years in Eruption
Roberta M. Humphreys, Terry J. Jones, Elisha Polomski +9
Variable A in M33 is a member of a rare class of highly luminous, evolved stars near the upper luminosity boundary that show sudden and dramatic shifts in apparent temperature due…
