A statistical and machine learning approach to the study of astrochemistry [PDF]
Faraday discussions, 2023 In order to obtain a good understanding of astrochemistry, it is crucial to better understand the key parameters that govern grain-surface chemistry. For many chemical networks, these crucial parameters are the binding energies of the species.

Astrochemistry of dimethyl ether [PDF]
Astronomy & Astrophysics, 2005 Dimethyl ether (DME, CH 3 OCH 3 ) is one of the largest organic molecules detected in the interstellar gas and shows high abundances in star-forming regions, known as hot molecular cores. The observed DME might be formed on grains or by secondary gas phase reactions from a precursor molecule, which in turn was sublimed into the gas phase from the grain

Laboratory surface astrochemistry experiments [PDF]
Review of Scientific Instruments, 2015 Although several research groups have studied the formation of H2 on interstellar dust grains using surface science techniques, few have explored the formation of more complex molecules. A small number of these reactions produce molecules that remain on the surface of interstellar dust grains and, over time, lead to the formation of icy mantles.

Interrelations Between Astrochemistry and Galactic Dynamics
Frontiers in Astronomy and Space Sciences, 2021 This paper presents a review of ideas that interconnect astrochemistry and galactic dynamics. Since these two areas are vast and not recent, each one has already been covered separately by several reviews.

Systems Astrochemistry: A New Doctrine for Experimental Studies
Frontiers in Astronomy and Space Sciences, 2021 Laboratory experiments play a key role in deciphering the chemistry of the interstellar medium (ISM) and the formation of complex organic molecules (COMs) relevant to life.

Cold CAS ion trap – 22 pole trap with ring electrodes for astrochemistry [PDF]
, 2023 The enhancement of a cryogenic radio frequency 22 pole trap instrument by the addition of ring electrodes is presented in detail. The ring electrodes tightly surround the poles and only a fraction of the applied electric potential penetrates to the trap ...
