Journal ArticleDOI
Rosseland and Planck mean opacities for protoplanetary discs
TL;DR: In this article, the mean gas and dust opacities relevant to the physical conditions typical of protoplanetary discs were calculated for temperatures between 5 K and 10 000 K and gas densities ranging from 10 −18 gc m −3 to 10 −7 gcm −3.
Journal ArticleDOI
Chemistry in Protoplanetary Disks
Thomas Henning,Dmitry Semenov +1 more
TL;DR: The results from (sub-)millimeter Spectroscopy and (near-infrared) spectroscopy were reported in this paper, showing that refractory grains and molecular Ices are important components of a gas phase molecule.
Journal ArticleDOI
Chemistry in disks - IV. Benchmarking gas-grain chemical models with surface reactions
Dmitry Semenov,Franck Hersant,Franck Hersant,Valentine Wakelam,Valentine Wakelam,Anne Dutrey,Anne Dutrey,E. Chapillon,Stéphane Guilloteau,Stéphane Guilloteau,Th. Henning,Ralf Launhardt,Vincent Piétu,Katharina Schreyer +13 more
TL;DR: In this paper, the authors describe and benchmark two sophisticated chemical models developed by the Heidelberg and Bordeaux astrochemistry groups and provide nonspecialists with a detailed description of the model ingredients and requirements to analyze the cosmic chemistry as studied.

Chemistry in Disks. IV. Benchmarking gas-grain chemical models with surface reactions
Dmitry Semenov,Franck Hersant,Valentine Wakelam,Anne Dutrey,E. Chapillon,Guilloteau,Th. Henning,Ralf Launhardt,Vincent Piétu,Katharina Schreyer +9 more
TL;DR: In this paper, the authors detail and benchmark two sophisticated chemical models developed by the Heidelberg and Bordeaux astrochemistry groups and compare them with the original gas-phase osu_03_2008 ratefile and a set of surface reactions for the H-, O-, C-, S-, and N-bearing molecules.
Journal ArticleDOI
Measuring Turbulence in TW Hya with ALMA: Methods and Limitations
Richard Teague,Stephane Guilloteau,Dmitry Semenov,Thomas Henning,Anne Dutrey,Vincent Piétu,Tilman Birnstiel,Edwige Chapillon,David Hollenbach,Uma Gorti +9 more
TL;DR: In this article, the radial distribution of the turbulent broadening is derived with three approaches: two direct and one modeling, which requires a single transition and derives \Tex{} directly from the line profile, yielding a \vturb{}.
