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…
The Spitzer c2d Survey of Nearby Dense Cores: I: First Direct Detection of the Embedded Source in IRAM 04191+1522
M. M. Dunham, N. J. Evans, T. L. Bourke +9
We report the first detections of the Class 0 protostellar source IRAM 04191+1522 at wavelengths shortward of 60 microns with the Spitzer Space Telescope. We see extended emission…
The Spitzer c2d Survey of Nearby Dense Cores: III: Low Mass Star Formation in a Small Group, L1251B
Jeong-Eun Lee, James Di Francesco, Shih-Ping Lai +8
We present a comprehensive study of a low-mass star-forming region,L1251B, at wavelengths from the near-infrared to the millimeter. L1251B, where only one protostar, IRAS 22376+745…
The Spitzer c2d Survey of Large, Nearby, Interstellar Clouds. III. Perseus Observed with IRAC
Jes K. Jorgensen, Paul M. Harvey, Neal J. Evans +19
We present observations of 3.86 sq. deg. of the Perseus molecular cloud complex with the Spitzer Space Telescope Infrared Array Camera (IRAC). The maps show strong extended emissio…
Weak-line T Tauri Star Disks I. Initial Spitzer Results from the Cores to Disks Legacy Project
D. L. Padgett, L. Cieza, K. R. Stapelfeldt +17
Using the Spitzer Space Telescope, we have observed 90 weak-line and classical T Tauri stars in the vicinity of the Ophiuchus, Lupus, Chamaeleon, and Taurus star-forming regions as…
