Identifying the Low Luminosity Population of Embedded Protostars in the c2d Observations of Clouds and Cores
Michael M. Dunham, Antonio Crapsi, Neal J. Evans +4
We present a search for all embedded protostars with internal luminosities < 1 solar luminosity in the sample of nearby, low-mass star-forming regions surveyed by the Spitzer Space…
The Mass Distribution and Lifetime of Prestellar Cores in Perseus, Serpens, and Ophiuchus
Melissa L. Enoch, Neal J. Evans, Anneila I. Sargent +3
We present an unbiased census of starless cores in Perseus, Serpens, and Ophiuchus, assembled by comparing large-scale Bolocam 1.1 mm continuum emission maps with Spitzer c2d surve…
The Spitzer c2d Survey of Large, Nearby, Interstellar Clouds. XI. Lupus Observed With IRAC and MIPS
Bruno Merin, Jes Jorgensen, Loredana Spezzi +7
We present c2d Spitzer/IRAC observations of the Lupus I, III and IV dark clouds and discuss them in combination with optical and near-infrared and c2d MIPS data. With the Spitzer d…
The young population of the Chamaeleon II dark cloud
Loredana Spezzi, Juan M. Alcala', Elvira Covino +9
We discuss the results of the optical spectroscopic follow-up of pre-main sequence (PMS) objects and candidates selected in the Chamaeleon II dark cloud based on data from the Spit…
The Spitzer c2d Survey of Large, Nearby, Interstellar Clouds.X. The Chamaeleon II Pre-Main Sequence Population as Observed With IRAC and MIPS
Juan M. Alcala', Loredana Spezzi, Nicholas Chapman +9
We discuss the results from the combined IRAC and MIPS c2d Spitzer Legacy survey observations and complementary optical and near infrared data of the Chamaeleon II (Cha II) dark cl…
H2O and OH gas in the terrestrial planet-forming zones of protoplanetary disks
C. Salyk, K. M. Pontoppidan, G. A. Blake +3
We present detections of numerous 10-20 micron H2O emission lines from two protoplanetary disks around the T Tauri stars AS 205A and DR Tau, obtained using the InfraRed Spectrograp…
