Journal ArticleDOI
Water Vapor in the Protoplanetary Disk of DG Tau
Linda Podio,Inga Kamp,Claudio Codella,Sylvie Cabrit,Brunella Nisini,Catherine Dougados,Catherine Dougados,Göran Sandell,Jonathan Williams,Leonardo Testi,W. F. Thi,Peter Woitke,Rowin Meijerink,Marco Spaans,Giambattista Aresu,Francois Menard,Francois Menard,Christophe Pinte +17 more
TL;DR: In this paper, the authors present spectrally resolved Herschel/HIFI observations of the young TTS DG Tau in the ortho-and para-water ground-state transitions at 557, 1113 GHz.
Journal ArticleDOI
Interstellar Ices as Witnesses of Star Formation: Selective Deuteration of Water and Organic Molecules Unveiled
TL;DR: In this article, the authors explain the selective deuteration of organic molecules and water by following the formation of ices in translucent clouds, as well as their evolution as the cloud collapses to form a star.
Journal ArticleDOI
Molecular hydrogen formation on dust grains in the high-redshift universe
Stéphanie Cazaux,Marco Spaans +1 more
TL;DR: In this paper, the formation of molecular hydrogen on dust grain surfaces and apply their results to the high-redshift universe was studied and it was found that a range of physical parameters such as dust temperature and gas temperature, but not so much dust surface composition, influenced the formation rate of H2.
Journal ArticleDOI
WATER VAPOR EMISSION REVEALS A HIGHLY OBSCURED, STAR-FORMING NUCLEAR REGION IN THE QSO HOST GALAXY APM 08279+5255 AT z = 3.9

TL;DR: In this paper, the authors present the detection of four rotational emission lines of water vapor, from energy levels E u/k = 101-454 K, in the gravitationally lensed z = 3.9 QSO host galaxy APM?08279+5255.
Journal ArticleDOI

White,Glenn J. White,David R. Ardila,Jean-Pierre Lebreton,I. Mendigutía,Sean D. Brittain +24 more
TL;DR: In this article, the authors constrain the gas and dust mass in the disk around HD141569A by modeling the continuum emission and the line fluxes with the Monte Carlo radiative transfer code MCFOST and the thermo-chemical code ProDiMo.
