8--13 um spectroscopy of YSOs: Evolution of the silicate feature
J. E. Kessler-Silacci, L. A. Hillenbrand, G. A. Blake +1
In order to investigate possible connections between dust processing and disk properties, 8--13 um spectra of 34 young stars, with a range of circumstellar environments and spectra…
Ices in the edge-on disk CRBR 2422.8-3423: Spitzer spectroscopy and Monte Carlo radiative transfer modeling
Klaus M. Pontoppidan, Cornelis P. Dullemond, Ewine F. van Dishoeck +5
We present 5.2-37.2 micron spectroscopy of the edge-on circumstellar disk CRBR 2422.8-3423 obtained using the InfraRed Spectrograph (IRS) of the Spitzer Space Telescope. The IRS sp…
A "Starless" Core that Isn't: Detection of a Source in the L1014 Dense Core with the Spitzer Space Telescope
C. H. Young, J. K. Joergensen, Y. L. Shirley +27
We present observations of L1014, a dense core in the Cygnus region previously thought to be starless, but data from the Spitzer Space Telescope shows the presence of an embedded s…
Spitzer Space Telescope Spectroscopy of Ices toward Low Mass Embedded Protostars
A. Boogert, K. Pontoppidan, F. Lahuis +23
Sensitive 5-38 um Spitzer Space Telescope (SST) and ground based 3-5 um spectra of the embedded low mass protostars B5 IRS1 and HH46 IRS show deep ice absorption bands superposed o…
Imaging the Disk around TW Hya with the Submillimeter Array
C. Qi, P. T. P. Ho, D. J. Wilner +10
We present ~2"-4" aperture synthesis observations of the circumstellar disk surrounding the nearby young star TW Hya in the CO J=2--1 and J=3--2 lines and associated dust continuum…
On the origin of H2CO abundance enhancements in low-mass protostars
F. L. Schoeier, J. K. Jorgensen, E. F. van Dishoeck +1
High angular resolution H2CO 218 GHz line observations have been carried out toward the low-mass protostars IRAS 16293-2422 and L1448-C using the Owens Valley Millimeter Array at ~…
