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-MIPS survey of the young stellar content in the Vela Molecular Cloud-D
T. Giannini, D. Lorenzetti, M. De Luca +8
A new, unbiased Spitzer-MIPS imaging survey (~1.8 square degs) of the young stellar content of the Vela Molecular Cloud-D is presented. The survey is complete down to 5mJy and 250m…
The Dust and Gas Around beta Pictoris
C. H. Chen, A. Li, C. Bohac +12
We have obtained Spitzer IRS 5.5 - 35 micron spectroscopy of the debris disk around beta Pictoris. In addition to the 10 micron silicate emission feature originally observed from t…
Discovery of Two T Dwarf Companions with the Spitzer Space Telescope
K. L. Luhman, B. M. Patten, M. Marengo +12
We report the discovery of T dwarf companions to the nearby stars HN Peg (G0V, 18.4 pc, ~0.3 Gyr) and HD 3651 (K0V, 11.1 pc, ~7 Gyr). During an ongoing survey of 5'x5' fields surro…
A Spitzer/IRAC Search for Substellar Companions of the Debris Disk Star epsilon Eridani
M. Marengo, S. T. Megeath, G. G. Fazio +3
We have used the InfraRed Array Camera (IRAC) onboard the Spitzer Space telescope to search for low mass companions of the nearby debris disk star epsilon Eridani. The star was obs…
Outflows from Massive YSOs as Seen with the Infrared Array Camera
Howard A. Smith, J. L. Hora, M. Marengo +1
The bipolar outflow from the massive star forming cluster in DR21 is one of the most powerful known, and in IRAC images the outflow stands out by virtue of its brightness at 4.5 um…
