Influence of galactic arm scale dynamics on the molecular composition of the cold and dense ISM II. Molecular oxygen abundance
V. Wakelam, M. Ruaud, P. Gratier +1
Molecular oxygen has been the subject of many observational searches as chemical models predicted it to be a reservoir of oxygen. Although it has been detected in two regions of th…
New constraints on the initial parameters of low-mass star formation from chemical modeling
Thomas H. G. Vidal, Pierre Gratier, Neil Vaytet +2
The complexity of physico-chemical models of star formation is increasing, with models that take into account new processes and more realistic setups. These models allow astrochemi…
A dynamically young, gravitationally stable network of filaments in Orion B
Jan H. Orkisz, Nicolas Peretto, Jérôme Pety +15
Filaments are a key step on the path that leads from molecular clouds to star formation. However, their characteristics are heavily debated, and the exact processes that lead to th…
Dissecting the molecular structure of the Orion B cloud: Insight from Principal Component Analysis
Pierre Gratier, Emeric Bron, Maryvonne Gerin +12
Context. The combination of wideband receivers and spectrometers currently available in (sub-)millimeter observatories deliver wide- field hyperspectral imaging of the interstellar…
Turbulence and star formation efficiency in molecular clouds: solenoidal versus compressive motions in Orion B
Jan H. Orkisz, Jérôme Pety, Maryvonne Gerin +13
The nature of turbulence in molecular clouds is one of the key parameters that control star formation efficiency: compressive motions, as opposed to solenoidal motions, can trigger…
Chemistry of TMC-1 with multiply deuterated species and spin chemistry of H2, H2+, H3+ and their isotopologues
L. Majumdar, P. Gratier, M. Ruaud +6
Deuterated species are unique and powerful tools in astronomy since they can probe the physical conditions, chemistry, and ionization level of various astrophysical media. Recent o…
