Epsilon Eridani's Planetary Debris Disk: Structure and Dynamics based on Spitzer and CSO Observations
D. Backman, M. Marengo, K. Stapelfeldt +9
Spitzer and Caltech Submillimeter Observatory (CSO) images and spectrophotometry of epsilon Eridani at wavelengths from 3.5 to 350 um reveal new details of its bright debris disk.…
Spitzer Observations of Bok Globule B335: Isolated Star Formation Efficiency and Cloud Structure
Amelia M. Stutz, Mark Rubin, Michael W. Werner +8
We present infrared and millimeter observations of Barnard 335, the prototypical isolated Bok globule with an embedded protostar. Using Spitzer data we measure the source luminosit…
Metallicity Effects on Dust Properties in Starbursting Galaxies
C. W. Engelbracht, G. H. Rieke, K. D. Gordon +5
We present infrared observations of 66 starburst galaxies over a wide range of oxygen abundances, to measure how metallicity affects their dust properties. The data include imaging…
Far-infrared polarimetry from the Stratospheric Observatory for Infrared Astronomy
J. E. Vaillancourt, D. T. Chuss, R. M. Crutcher +8
Multi-wavelength imaging polarimetry at far-infrared wavelengths has proven to be an excellent tool for studying the physical properties of dust, molecular clouds, and magnetic fie…
The Relationship between the Optical Depth of the 9.7 micron Silicate Absorption Feature and Infrared Differential Extinction in Dense Clouds
J. E. Chiar, K. Ennico, Y. J. Pendleton +8
We have examined the relationship between the optical depth of the 9.7 micron silicate absorption feature (tau_9.7) and the near-infrared color excess, E(J-Ks) in the Serpens, Taur…
Far Infrared Prperties of M Dwarfs
Thomas. N. Gautier, G. H. Rieke, John Stansberry +9
We report the mid- and far-infrared properties of nearby M dwarfs. Spitzer/MIPS measurements were obtained for a sample of 62 stars at 24 um, with subsamples of 41 and 20 stars obs…
