Astrochemistry: the issue of molecular complexity in astrophysical environments [PDF]

2013, Bull. Soc. R. Sci. Li\`ege, 82, 33-94, 2013
Astrochemistry aims at studying chemical processes in astronomical environments. This discipline -- located at the crossroad between astrophysics and chemistry -- is rapidly evolving and explores the issue of the formation of molecules of increasing complexity in particular physical conditions that deviate significantly from those frequently ...

Warm Cores around Regions of Low-Mass Star Formation

, 2010
Warm cores (or hot corinos) around low-mass protostellar objects show a rich chemistry with strong spatial variations. This chemistry is generally attributed to the sublimation of icy mantles on dust grains initiated by the warming effect of the stellar ...

Experimental studies of nucleation and growth processes related to the formation of presolar grains [PDF]

An understanding was sought for the mechanisms of nucleation of refractory materials, and the relative importance of factors controlling the rate of cluster formation and growth for astrophysically important species.

Astrochemistry: From primordial gas to present-day clouds [PDF]

arXiv, 2017
Astrochemistry plays a central role during the process of star formation, both in the primordial regime as well as in the present-day Universe. We revisit here the chemistry in both regimes, focusing first on the chemistry under close to primordial conditions, as observed in the so-called Caffau star SDSS J102915+172927, and subsequently discuss ...

Infrared Spectroscopic and Physical Properties of Methanol Ices—Reconciling the Conflicting Published Band Strengths of an Important Interstellar Solid

The Astrophysical Journal
Infrared spectroscopic observations have established the presence of solid methanol (CH _3 OH) in the interstellar medium and in solar system ices, but the abundance of frozen CH _3 OH cannot be deduced without accurate band strengths, optical constants,

Effect of nuclear spin symmetry in cold and ultracold reactions: D + para/ortho-H2

New Journal of Physics, 2015
We report results for reaction and vibrational quenching of the collision D with para-H _2 ( $v,j=0$ ) and ortho-H _2 ( $v,j=1$ ) at cold and ultracold temperatures.
