The Spitzer c2d Legacy Results: Star Formation Rates and Efficiencies; Evolution and Lifetimes
Neal J. Evans, Michael M. Dunham, Jes K. Jørgensen +15
(Abridged) The c2d Spitzer Legacy project obtained images and photometry with both IRAC and MIPS instruments for five large, nearby molecular clouds. This paper combines informatio…
Probing dust grain evolution in IM Lupi's circumstellar disc. Multi-wavelength observations and modelling of the dust disc
C. Pinte, D. L. Padgett, F. Menard +19
We present a panchromatic study, involving a multiple technique approach, of the circumstellar disc surrounding the T Tauri star IM Lupi (Sz 82). We have undertaken a comprehensive…
Absolute Calibration and Characterization of the Multiband Imaging Photometer for Spitzer: IV. The Spectral Energy Distribution Mode
N. Lu, P. S. Smith, C. W. Engelbracht +12
The Spectral Energy Distribution (SED) mode of the Multiband Imaging Photometer for Spitzer (MIPS) Space Telescope provides low-spectral resolution (R ~ 15-25) spectroscopy in the…
Submillimeter Structure of the Disk of the Butterfly Star
S. Wolf, A. Schegerer, H. Beuther +2
We present a spatially resolved 894 micron map of the circumstellar disk of the Butterfly star in Taurus (IRAS 04302+2247), obtained with the Submillimeter Array (SMA). The predict…
The c2d Spitzer spectroscopy survey of ices around low-mass young stellar objects, III: CH4
Karin I. Oberg, A. C. Adwin Boogert, Klaus M. Pontoppidan +4
CH4 is proposed to be the starting point of a rich organic chemistry. Solid CH4 abundances have previously been determined mostly toward high mass star forming regions. Spitzer/IRS…
The c2d Spitzer Spectroscopic Survey of Ices Around Low-Mass Young Stellar Objects: I. H2O and the 5-8 um Bands
A. Boogert, K. Pontoppidan, C. Knez +23
With the goal to study the physical and chemical evolution of ices in solar-mass systems, a spectral survey is conducted of a sample of 41 low luminosity YSOs using 3-38 um Spitzer…
