TLDR
The UMIST Database for Astrochemistry (UDfaa) as discussed by the authors contains 6173 gas-phase reactions involving 467 species, 47 of which are new to this release.Abstract:
We present the fifth release of the UMIST Database for Astrochemistry (UDfA). The new reaction network contains 6173 gas-phase reactions, involving 467 species, 47 of which are new to this release. We have updated rate coefficients across all reaction types. We have included 1171 new anion reactions and updated and reviewed all photorates. In addition to the usual reaction network, we also now include, for download, state-specific deuterated rate coefficients, deuterium exchange reactions and a list of surface binding energies for many neutral species. Where possible, we have referenced the original source of all new and existing data. We have tested the main reaction network using a dark cloud model and a carbon-rich circumstellar envelope model. We present and briefly discuss the results of these models.read more

The Nine Lives of Cosmic Rays in Galaxies
TL;DR: The impact of low-energy cosmic rays on interstellar chemistry is a fast-developing topic, including the propagation of these particles into the clouds in which the chemistry occurs as mentioned in this paper.
The UMIST database for astrochemistry 1999
TL;DR: The UMIST database as mentioned in this paper contains the rate coefficients, temperature ranges and temperature dependence of 4113 gas-phase reactions important in astrophysical environments, including ionisation, dissociation, fragmentation and Deuterium fractionation.

Radiation magnetohydrodynamic simulations of protostellar collapse: nonideal magnetohydrodynamic effects and early formation of circumstellar disks
TL;DR: In this paper, the authors performed three-dimensional nested-grid radiation magnetohydrodynamic simulations including ambipolar diffusion and ohmic dissipation and found that these effects work effectively in almost the entire region within the first core and significant magnetic flux loss occurs.

A survey of interstellar H I from L-alpha absorption measurements. II
TL;DR: The Copernicus satellite surveyed the spectral region near L alpha to obtain column densities of interstellar HI toward 100 stars as discussed by the authors, and the value of the mean ratio of total neutral hydrogen to color excess was found to equal 5.8 x 10 to the 21st power atoms per (sq cm x mag).
