Low Mass Star Formation in the Taurus-Auriga Clouds
Scott J. Kenyon, Mercedes Gomez, Barbara A. Whitney
We review the history and structure of star formation in the Taurus-Auriga dark clouds. Our discussion includes a summary of the macroscopic cloud properties, the population of sin…
Infrared point source variability between the Spitzer and MSX surveys of the Galactic mid-plane
Thomas P. Robitaille, Martin Cohen, Barbara A. Whitney +4
We present a list of 552 sources with suspected variability, based on a comparison of mid-infrared photometry from the GLIMPSE I and MSX surveys, which were carried out nearly a de…
The Spitzer Survey of the Small Magellanic Cloud: Discovery of Embedded Protostars in the HII Region NGC 346
Joshua D. Simon, Alberto D. Bolatto, Barbara A. Whitney +6
We use Spitzer Space Telescope observations from the Spitzer Survey of the Small Magellanic Cloud (S3MC) to study the young stellar content of N66, the largest and brightest HII re…
Molecular Outflows and a Mid-Infrared Census of the Massive Star-Formation Region Associated with IRAS 18507+0121
D. S. Shepherd, M. S. Povich, B. A. Whitney +7
We have observed the central region of the IR-dark cloud filament associated with IRAS 18507+0121 at millimeter wavelengths in CO(1-0), 13CO(1-0), and C18O(1-0) line emission and w…
The Frequency of Mid-Infrared Excess Sources in Galactic Surveys
B. Uzpen, H. A. Kobulnicky, A. J. Monson +27
We have identified 230 Tycho-2 Spectral Catalog stars that exhibit 8 micron mid-infrared extraphotospheric excesses in the MidCourse Space Experiment (MSX) and Spitzer Space Telesc…
2-D Models of Protostars: III. Effects of Stellar Temperature
Barbara. A. Whitney, Remy Indebetouw, J. E. Bjorkman +1
We model how the mid-infrared colors of Young Stellar Objects (YSOs) vary with stellar temperature. The spectral energy distribution (SED) of each object has contributions from the…
