SCUBA Mapping of Spitzer c2d Small Clouds and Cores
C. H. Young, T. L. Bourke, K. E. Young +6
We present submillimeter observations of dark clouds that are part of the Spitzer Legacy Program, From Molecular Cores to Planet-Forming Disks (c2d). We used the Submillimetre Comm…
Spitzer-IRS spectra of disks around T Tauri stars II. PAH emission features
V. C. Geers, J. -C. Augereau, K. M. Pontoppidan +10
Aims: We search for PAH features towards T Tauri stars and compare them with surveys of Herbig Ae/Be stars. The presence and strength of the PAH features are interpreted with disk…
The Spitzer c2d Survey of Nearby Dense Cores: II: Discovery of a Low Luminosity Object in the "Evolved Starless Core" L1521F
Tyler L. Bourke, Philip C. Myers, Neal J. Evans +12
We present Spitzer Space Telescope observations of the "evolved starless core" L1521F which reveal the presence of a very low luminosity object (L < 0.07 Lsun). The object, L1521F-…
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…
