Journal ArticleDOI

Edwin A. Bergin,L. Ilsedore Cleeves,U. Gorti,U. Gorti,Ke Zhang,Geoffrey A. Blake,Joel D. Green,Sean M. Andrews,Neal J. Evans,Thomas Henning,Karin I. Öberg,Klaus M. Pontoppidan,Chunhua Qi,Colette Salyk,Ewine F. van Dishoeck +14 more
TL;DR: The detection of hydrogen deuteride, combined with existing observations and detailed models, implies a disk mass of more than 0.05 solar masses, which is enough to form a planetary system like the authors' own.
Journal ArticleDOI
Detection of the water reservoir in a forming planetary system
Michiel R. Hogerheijde,Edwin A. Bergin,Christian Brinch,L. Ilsedore Cleeves,Jeffrey K. J. Fogel,Geoffrey A. Blake,Carsten Dominik,Dariusz C. Lis,Gary J. Melnick,David A. Neufeld,Olja Panić,John C. Pearson,Lars E. Kristensen,Umut A. Yildiz,Ewine F. van Dishoeck +14 more
TL;DR: The Heterodyne Instrument for the Far-Infrared on board the Herschel Space Observatory has detected emission lines from both spin isomers of cold water vapor from the disk around the young star TW Hydrae, hinting at a water ice reservoir equivalent to several thousand Earth oceans in mass.
Journal ArticleDOI
Exclusion of Cosmic Rays in Protoplanetary Disks: Stellar and Magnetic Effects
TL;DR: In this paper, the effects of stellar winds and magnetic field structures on disk ionization rates were investigated in a T-Tauri star system, and it was shown that stellar winds can power a heliosphere-like analog, i.e., a Tauriosphere, diminishing the ionization rate of the disk.
Journal ArticleDOI
The ancient heritage of water ice in the solar system.
L. Ilsedore Cleeves,Edwin A. Bergin,Conel M. O'd. Alexander,Fujun Du,Dawn Graninger,Karin I. Öberg,Tim J. Harries +6 more
TL;DR: Using a comprehensive treatment of disk ionization, it is found that ion-driven deuterium pathways are inefficient, which curtails the disk's deuterated water formation and its viability as the sole source for the solar system’s water.
Journal ArticleDOI
The radial distribution of h2 and co in tw hya as revealed by resolved alma observations of co isotopologues

TL;DR: In this article, the surface CO snowline at ~30 AU and an outer ring of CO emission centered at 53 AU were obtained from resolved ALMA observations of CO 3-2, C^(18)O 3 -2, CO 6-5, and CO 6 -5 emission in TW Hya.
