The Neon Abundance of Galactic Wolf-Rayet Stars
J. D. T. Smith, J. R. Houck
The fast, dense winds which characterize Wolf-Rayet (WR) stars obscure their underlying cores, and complicate the verification of evolving core and nucleosynthesis models. Core evo…
The SMART Data Analysis Package for the Infrared Spectrograph on the Spitzer Space Telescope
S. J. U. Higdon, D. Devost, J. L. Higdon +8
SMART is a software package written in IDL to reduce and analyze Spitzer data from all four modules of the Infrared Spectrograph, including the peak-up arrays. The software is desi…
New Infrared Emission Features and Spectral Variations in NGC 7023
M. W. Werner, K. I. Uchida, K. Sellgren +5
We have observed the reflection nebula NGC 7023, with the Short-High module and long-slit Short-Low and Long-Low modules of the Infrared Spectrograph on the Spitzer Space Telescope…
Spitzer-IRS Spectroscopy of the Prototypical Starburst Galaxy NGC7714
B. R. Brandl, D. Devost, S. J. U. Higdon +11
We present observations of the starburst galaxy NGC 7714 with the Infrared Spectrograph IRS on board the Spitzer Space Telescope. The spectra yield a wealth of ionic and molecular…
First mid-infrared spectrum of a faint high-z galaxy: Observations of CFRS 14.1157 with the Infrared Spectrograph on the Spitzer Space Telescope
S. J. U. Higdon, D. Weedman, J. L. Higdon +7
The unprecedented sensitivity of the Infrared Spectrograph on the Spitzer Space Telescope allows for the first time the measurement of mid-infrared spectra from 14 to 38 microns of…
Spitzer Infrared Spectrograph Observations of M, L, and T Dwarfs
T. L. Roellig, J. E. Van Cleve, G. C. Sloan +8
We present the first mid-infrared spectra of brown dwarfs, together with observations of a low-mass star. Our targets are the M3.5 dwarf GJ 1001A, the L8 dwarf DENIS-P J0255-4700,…
