Pre-Main Sequence variables in the VMR-D : identification of T Tauri-like accreting protostars through Spitzer-IRAC variability
T. Giannini, D. Lorenzetti, D. Elia +6
We present a study of the infrared variability of young stellar objects by means of two Spitzer-IRAC images of the Vela Molecular Cloud D (VMR-D) obtained in observations separated…
Imaging the Cool Hypergiant NML Cygni's Dusty Circumstellar Envelope with Adaptive Optics
M. T. Schuster, M. Marengo, J. L. Hora +6
We present sub-arcsec angular resolution, high-Strehl ratio mid-IR adaptive optics images of the powerful OH/IR source and cool hypergiant NML Cyg at 8.8, 9.8 and 11.7 um. These im…
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…
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…
The Vega Debris Disk -- A Surprise from Spitzer
K. Y. L. Su, G. H. Rieke, K. A. Misselt +13
We present high spatial resolution mid- and far-infrared images of the Vega debris disk obtained with the Multiband Imaging Photometer for Spitzer (MIPS). The disk is well resolved…
