Multiple paths of deuterium fractionation in protoplanetary disks
Yuri Aikawa, Kenji Furuya, Ugo Hincelin +1
We investigate deuterium chemistry coupled with the nuclear spin-state chemistry of H and H in protoplanetary disks. Multiple paths of deuterium fractionation are found;…
A New and Simple Approach to Determine the Abundance of Hydrogen Molecules on Interstellar Ice Mantles
Ugo Hincelin, Qiang Chang, Eric Herbst
Water is usually the main component of ice mantles, which cover the cores of dust grains in cold portions of dense interstellar clouds. When molecular hydrogen is adsorbed onto an…
Water deuterium fractionation in the high-mass star-forming region G34.26+0.15 based on Herschel/HIFI data
Audrey Coutens, Charlotte Vastel, Ugo Hincelin +8
Understanding water deuterium fractionation is important for constraining the mechanisms of water formation in interstellar clouds. Observations of HDO and HO transitions…
Survival of interstellar molecules to prestellar dense core collapse and early phases of disk formation
Ugo Hincelin, Valentine Wakelam, Benoît Commerçon +2
An outstanding question of astrobiology is the link between the chemical composition of planets, comets, and other solar system bodies and the molecules formed in the interstellar…
Oxygen depletion in dense molecular clouds: a clue to a low O2 abundance?
U. Hincelin, V. Wakelam, F. Hersant +4
Context: Dark cloud chemical models usually predict large amounts of O2, often above observational limits. Aims: We investigate the reason for this discrepancy from a theoretical p…
