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.

Interstellar medium simulations
Astronomische Nachrichten, 2012AbstractIn this review we critically assess numerical simulations of the interstellar medium (ISM), and argue that 3D high resolution calculations are the most promising method to determine the structure of the interstellar gas and follow its evolution well into the nonlinear regime. Based on a Riemann solver adaptive mesh refinement code, we present a

This report summarizes the issues discussed in Working Group VI concerning the accuracy of measurements of D/H and 3He/H in the local interstellar medium, possible systematic errors, and emerging trends in the results.

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.

Obwohl die meiste Masse im Milchstrasensystem in den Sternen enthalten ist, ist der interstellare Raum nicht vollkommen leer. Er enthalt Gas und Staub. Beide Bestandteile sind teilweise diffus verteilt, teilweise in einzelnen Wolken konzentriert. Typisch fur den interstellaren Raum ist eine mittlere Dichte von einem Gasatom pro Kubikzentimeter und ...

NEUTRAL interstellar hydrogen can be prevented from penetrating freely into the heliosphere of solar plasma, because it is partially coupled to the subsonic flow of interstellar plasma. Results from modelling the backscattering of the diffuse Lyman-α radiation are therefore unreliable.

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 ...
