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…
The c2d Spitzer spectroscopic survey of ices around low-mass young stellar objects II: CO2
Klaus M. Pontoppidan, A. C. A. Boogert, Helen J. Fraser +6
This paper presents Spitzer-IRS spectroscopy of the CO2 15.2 micron bending mode toward a sample of 50 embedded low-mass stars in nearby star-forming clouds, taken mostly from the…
Probing Protoplanetary Disks with Silicate Emission: Where is the silicate emission zone?
J. E. Kessler-Silacci, C. P. Dullemond, J. -C. Augereau +6
Recent results indicate that the grain size and crystallinity inferred from observations of silicate features may be correlated with spectral type of the central star and/or disk g…
The Spitzer c2d survey of Large, Nearby, Interstellar Clouds. V. Chamaeleon II Observed with IRAC
Alicia Porras, Jes K. Jørgensen, Lori E. Allen +19
We present IRAC (3.6, 4.5, 5.8, and 8.0 micron) observations of the Chamaeleon II molecular cloud. The observed area covers about 1 square degree defined by . Analysis of t…
The Spitzer c2d Survey of Nearby Dense Cores: IV. Revealing the Embedded Cluster in B59
Timothy Y. Brooke, Tracy L. Huard, Tyler L. Bourke +22
Infrared images of the dark cloud core B59 were obtained with the Spitzer Space Telescope as part of the "Cores to Disks" Legacy Science project. Photometry from 3.6-70 microns ind…
