Oxygen depletion in dense molecular clouds: a clue to a low O-2 abundance?
U. Hincelin,U. Hincelin,Valentine Wakelam,Valentine Wakelam,F. Hersant,F. Hersant,Stéphane Guilloteau,Stéphane Guilloteau,Jean-Christophe Loison,Jean-Christophe Loison,Pascal Honvault,Pascal Honvault,Jürgen Troe +12 more
TL;DR: In this article, the authors used the gas-grain code Nautilus with an up-to-date gas-phase network to study the sensitivity of the molecular oxygen abundance to the oxygen elemental abundance.

TL;DR: In this paper, the molecular content and chemistry of a circumstellar disk surrounding the Herbig A0 star AB Aur at (sub-)millimeter wavelengths were studied using an iterative minimization technique.

TL;DR: In this article, the molecular content and chemistry of a circumstellar disk surrounding the Herbig Ae star AB Aur at (sub-)millimeter wavelengths were studied using the IRAM Plateau de Bure Interferometer in the C- and D-configurations in rotational lines of CS, HCN, C2H, CH3OH, and CO isotopes.
On the dynamics of resonant super-Earths in disks with turbulence driven by stochastic forcing
TL;DR: In this paper, the authors investigated the evolution of a system of two super-Earths embedded in a turbulent protoplanetary disk and examined whether resonant trapping can be maintained in the presence of turbulence and how this depends on the amplitude of the stochastic density fluctuations in the disk.
On the dynamics of resonant super-Earths in disks with turbulence driven by stochastic forcing
TL;DR: In this paper, the authors investigate the evolution of a system of two super-Earths with masses 2x10−3 and find that the evolution can eventually involve temporary capture in a 8:7 commensurability but no stable MMR is formed.
