Measurements of water surface snow lines in classical protoplanetary disks
Sandra M. Blevins, Klaus M. Pontoppidan, Andrea Banzatti +5
We present deep Herschel-PACS spectroscopy of far-infrared water lines from a sample of four protoplanetary disks around solar-mass stars, selected to have strong water emission at…
Nonlinear TeraHertz Coherent Excitation of Vibrational Modes of Liquids
Marco A. Allodi, Ian A. Finneran, Geoffrey A. Blake
We report the first coherent excitation of intramolecular vibrational modes via the nonlinear interaction of a TeraHertz (THz) light field with molecular liquids. A terahertz-terah…
CSO and CARMA Observations of L1157. I. A Deep Search for Hydroxylamine (NHOH)
Brett A. McGuire, P. Brandon Carroll, Niklaus M. Dollhopf +7
A deep search for the potential glycine precursor hydroxylamine (NHOH) using the Caltech Submillimeter Observatory (CSO) at mm and the Combined Array for Research in M…
Detection of water vapor in the terrestrial planet forming region of a transition disk
Colette Salyk, John H. Lacy, Matthew J. Richter +3
We report a detection of water vapor in the protoplanetary disk around DoAr 44 with the Texas Echelon Cross Echelle Spectrograph --- a visitor instrument on the Gemini north telesc…
Tracing the Ingredients for a Habitable Earth from Interstellar Space through Planet Formation
Edwin A. Bergin, Geoffrey A. Blake, Fred Ciesla +2
We use the C/N ratio as a monitor of the delivery of key ingredients of life to nascent terrestrial worlds. Total elemental C and N contents, and their ratio, are examined for the…
Herschel observations of EXtra-Ordinary Sources: Analysis of the HIFI 1.2 THz Wide Spectral Survey Toward Orion KL II. Chemical Implications
Nathan R. Crockett, Edwin A. Bergin, Justin L. Neill +5
We present chemical implications arising from spectral models fit to the Herschel/HIFI spectral survey toward the Orion Kleinmann-Low nebula (Orion KL). We focus our discussion on…
