, 2018 This paper reports the first extensive study of the existence and effects of interstellar hydrogen bonding. The reactions that occur on the surface of the interstellar dust grains are the dominant processes by which interstellar molecules are formed ...

Metallic species in the interstellar medium: Astrochemical modeling
International audienceMetal-bearing species in diffuse or molecular clouds are often overlooked in astrochemical modeling except for the charge exchange process. However, catalytic cycles involving these metals can affect the abundance of other compounds.

The Abundance of Mg in the Interstellar Medium
, 1997 An empirical determination of the f-values of the far-UV Mg II lines at 1239 A and 1240 A is reported. The strong near-UV Mg II lines at 2796 A and 2803 A are generally highly saturated along most interstellar sightlines outside the local ISM and usually yield extremely uncertain estimates of Mg II column densities in interstellar gas.

Observations of interstellar zinc
, 1981 The International Ultraviolet Explorer observations of interstellar zinc toward 10 stars are examined. It is found that zinc is at most only slightly depleted in the interstellar medium; its abundance may serve as a tracer of the true metallicity in the ...

Indirect observation of unobservable interstellar molecules
, 1977 It is suggested that the abundances of neutral non-polar interstellar molecules unobservable by radio astronomy can be systematically determined by radio observation of the protonated ions.

H2cs Abundances And Ortho-to-para Ratios In Interstellar Clouds
, 1991 The published version is located at http://adsabs.harvard.edu/full/1991A%26A...244..181MSeveral H2CS ortho and para transitions have been observed toward interstellar molecular clouds, including cold, dark clouds and star-forming regions. H2CS fractional

Cosmic-Ray Spectra in Interstellar Space [PDF]
, 2004 At energies below ~300 MeV/nuc our knowledge of cosmic-ray spectra outside the heliosphere is obscured by the energy loss that cosmic rays experience during transport through the heliosphere into the inner solar system.
