Except in particular situations, the behaviour of ordinary gases is adiabatic. In fact, due to the low values of the viscosity coefficients and thermal conductivity there is no thermal contact with the surrounding medium and the dissipation of energy by viscosity is negligible.

Space Science Reviews, 2005
Infrared spectroscopy and photometry with ISO covering most of the emission range of the interstellar medium has led to important progress in the understanding of the physics and chemistry of the gas, the nature and evolution of the dust grains and also the coupling between the gas and the grains.

Oxygen in the Interstellar Medium
Reviews in Mineralogy and Geochemistry, 2008The oxygen that is observed in the Solar System today is a remnant of the interstellar oxygen that was in the dense molecular cloud that collapsed to form the Solar System. While the chemical evolution of the Galaxy has progressed since then, processes in the interstellar medium (ISM) that involve oxygen are relevant to the origins of oxygen in the ...

Astrophysics of the Interstellar Medium
2021This book is based on a series of lectures for an Astrophysics of the Interstellar Medium (ISM) master’s degree in Astrophysics and Cosmology at Padova University. From the cold molecular phase in which stars and planetary systems form, to the very hot coronal gas that surrounds galaxies and galaxy clusters, the ISM is everywhere.

Although most of the mass of the Milky Way Galaxy is condensed into stars, interstellar space is not completely empty. It contains gas and dust, in the form both of individual clouds and of a diffuse medium. Interstellar space typically contains about one gas atom per cubic centimetre and 100 dust particles per cubic kilometre.

Small missions for energetic astrophysics, 1999
The study of the interstellar medium has been, and remains, a rich field for exploitation using small missions in the ultraviolet and X-ray spectral regions. I review the history of some such missions (of various sizes), and I also review the capabilities for study of the interstellar medium of “Hot Universe Background Explorer” (HUBE), as it was ...

This chapter gives a brief introduction on the interstellar medium (ISM). It starts with an overview (Sect. 1.1) of the ISM properties including some worth-mentioning historical events that took place during its discovery and exploration. We then highlight the importance of the dust in ISM (Sect.

The global structure of the interstellar medium
Astrophysics and Space Science, 1994In the context of a review of work on the global structure of the interstellar medium, supernova remnant evolution, flows in multiphase media, cosmic ray moderation of flows, theories of the Galactic halo gas, and the nature of the local superbubble are considered.
