We describe the 2017 release of the spectral synthesis code CLOUDY, summarizing the
many improvements to the scope and accuracy of the physics which have been made since …

Molecule formation and infrared emission in fast interstellar shocks. III - Resu ADS Classic is
now deprecated. It will be completely retired in October 2019. This page will automatically …

We present the revised" Meudon" model of photon-dominated region (PDR) code, available
on the Web under the GNU Public License. General organization of the code is described …

Neutral gas in the central 2 parsecs of the Galaxy ADS Classic is now deprecated. It will be
completely retired in October 2019. This page will automatically redirect to the new ADS interface …

Abstract A fully sampled, 1000-point, 1-arcmin-resolution map of the inner 6.5 x 10 arcmin
(alpha x delta) regions of the Orion Nebula in the 157.7409-micron forbidden fine-structure …

The authors present the results of ab initio (SCF and CEPA) calculations of the interaction
potentials for the C (3 P)-H 2 (1 Sigma g+) system. The five potential curves corresponding …

We present far infrared (45-195 μm) spectrophotometric observations with the ISO-LWS of
the active star forming ρOph main cloud (L 1688). The [CII] 158 μm and [OI] 63 μm lines were …

We calculate theoretical population ratios of the ground fine-structure levels of some
atoms/ions which typically exhibit ultraviolet (UV) lines in the spectra of quasi-stellar objects …

In the lower atmosphere of Earth, oxygen contains a higher fraction of the heavy O 18
isotope than ocean water does (Dole effect). This isotopic enrichment is a signature of …

A new model of interstellar silicon chemistry is presented that explains the lack of SiO
detections in cold clouds and contains an exponential temperature dependence for the SiO …
