H₂ in Space

Flower, D.R.

Abstract

From 28 September to 1 October 1999, an international conference entitled 'H2 in Space' was held at the Institut d'Astrophysique in Paris. The meeting reviewed the current state of knowledge of the theoretical, experimental and observational properties of molecular hydrogen, with a view to obtaining a better understanding of H2 in Galactic and extragalactic environments. Molecular hydrogen may be excited by collisions with other particles (as in shock waves), by ultraviolet pumping (as in photon-dominated regions: PDR's), through its formation on the surfaces of dust grains (in interstellar clouds), or by absorption of the cosmic background radiation (in the primordial gas). We shall summarize the adequacy, or otherwise, of our knowledge of H2 (and HD), from the viewpoint of being able to reliably predict the spectrum arising from each of these excitation mechanisms.
