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…
Evolution of Chemistry and Molecular Line Profile during Protostellar Collapse
Jeong-Eun Lee, Edwin A. Bergin, Neal J. Evans
Understanding the chemical evolution in star-forming cores is a necessary pre-condition to correctly assess physical conditions when using molecular emission. We follow the evoluti…
Probing Pre-Protosellar Cores with Formaldehyde
Kaisa E. Young, Jeong-Eun Lee, Neal J. Evans +2
We present maps of the 6 cm and 1.3 mm transitions of formaldehyde toward three cold, dense pre-protostellar cores: L1498, L1512, and L1544. The 6 cm transition is a unique probe o…
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…
