SWAS Observations of Water in Molecular Outflows
J. Franklin, R. L. Snell, M. J. Kaufman +4
We present SWAS detections of the ground-state 1(10)-1(01) transition of o-H2O at 557 GHz in 18 molecular outflows. These results are combined with ground-based observations of the…
Fully Sampled Maps of Ices and Silicates in Front of Cepheus A East with Spitzer
P. Sonnentrucker, D. A. Neufeld, P. A. Gerakines +5
We report the first fully sampled maps of the distribution of interstellar CO2 ices, H2O ices and total hydrogen nuclei, as inferred from the 9.7 micron silicate feature, toward th…
Using Chemistry to Unveil the Kinematics of Starless Cores: Complex Radial Motions in Barnard 68
Sébastien Maret, Edwin A. Bergin, Charles J. Lada
We present observations of 13CO, C18O, HCO+, H13CO+, DCO+ and N2H+ line emission towards the Barnard 68 starless core. The line profiles are interpreted using a chemical network co…
The 10^5Lsun High-Mass Protostellar Object IRAS23151+5912
H. Beuther, Q. Zhang, T. R. Hunter +2
While most sources above 10^5Lsun have already formed an Ultracompact HII region (UCHII), this is not necessarily the case for sources of lower luminosity. Characterizing sources i…
Probing the Dust and Gas in the Transitional Disk of CS Cha with Spitzer
Catherine Espaillat, Nuria Calvet, Paola D'Alessio +10
Here we present the Spitzer IRS spectrum of CS Cha, a member of the ~2 Myr old Chamaeleon star-forming region, which reveals an optically thick circumstellar disk truncated at ~43…
Cold Dark Clouds: The Initial Conditions for Star Formation
Edwin A. Bergin, Mario Tafalla
Cold dark clouds are nearby members of the densest and coldest phase in the galactic interstellar medium, and represent the most accessible sites where stars like our Sun are curre…
