H2 formation on interstellar dust grains: The viewpoints of theory, experiments, models and observations
Valentine Wakelam,Emeric Bron,Emeric Bron,Stéphanie Cazaux,Stéphanie Cazaux,François Dulieu,Cecile Gry,Pierre Guillard,E. Habart,Liv Hornekær,Sabine Morisset,Gunnar Nyman,Valerio Pirronello,Stephen D. Price,Valeska Valdivia,Gianfranco Vidali,Naoki Watanabe +16 more
TL;DR: In this paper, the authors present what they think we know about the H2 formation in a variety of interstellar environments, in the perspective of the probable revolution brought by the future satellite JWST.

Low dust emissivities and radial variations in the envelopes of Class 0 protostars: a signature of early grain growth?
TL;DR: In this article, the authors analyzed PdBI observations at 1.3 and 3.2 mm for 12 Class 0 protostars obtained as part of the CALYPSO survey and derived dust emissivity index (beta) profiles as a function of the envelope radius at 200-2000 au scales.
3D chemical structure of diffuse turbulent ISM. I. Statistics of the HI-to-H$_2$ transition
Elena Bellomi,Benjamin Godard,Patrick Hennebelle,Valeska Valdivia,Guillaume Pineau des Forêts,Pierre Lesaffre,M. Perault +6 more
TL;DR: In this paper, the statistical properties of the HI-to-H$_2$ transition observed in absorption in the local diffuse and multiphase ISM to identify the physical processes controlling the probability of occurrence of any line of sight were studied.
Calibrating the Davis-Chandrasekhar-Fermi Method with Numerical Simulations: Uncertainties in Estimating the Magnetic Field Strength from Statistics of Field Orientations
TL;DR: In this article, the authors present a set of 3D MHD simulations and synthetic polarization images using radiative transfer of clustered massive star-forming regions and apply the DCF method on the synthetic polarization maps to investigate its reliability in high-density molecular clumps and dense cores where selfgravity is significant.

3D chemical structure of diffuse turbulent ISM - I. Statistics of the HI-to-H2 transition
Elena Bellomi,Elena Bellomi,B. Godard,B. Godard,Patrick Hennebelle,Valeska Valdivia,G. Pineau des Forêts,G. Pineau des Forêts,Pierre Lesaffre,Michel Perault +9 more
TL;DR: In this paper, the authors studied the statistical properties of the HI-to-H2 transition observed in absorption in the local diffuse and multiphase ISM and found that the lengths of the lines of sight follow a flat distribution in logarithmic scale from ~100 pc to 3 kpc.
