Interstellar cloud collisions [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1985
On decrit les resultats d'une simulation numerique en 3 dimensions de nuages interstellaires isothermes en l'absence de champs magnetiques. Les collisions, en general, ne donnent pas naissance a un ou plusieurs nuages.

Turbulence in the interstellar medium [PDF]

open access: yes, 2014
Turbulence is ubiquitous in the insterstellar medium and plays a major role in several processes such as the formation of dense structures and stars, the stability of molecular clouds, the amplification of magnetic fields, and the re-acceleration and ...

Turbulence in Interstellar Clouds [PDF]

open access: yesInternational Astronomical Union Colloquium, 1989
Above masses of the order of lOO M⊙, molecular clouds have masses and sizes which scale like those of self-gravitating polytropes bounded by an external pervading pressure. It is unlikely that this scaling is due to mere observational bias. But the physics underlying this behaviour is far from being understood.

Interstellar Scintillation and Clouds of the Interstellar Turbulent Plasma [PDF]

open access: yesInternational Astronomical Union Colloquium, 2001
AbstractData on interstellar diffraction and refraction scintillation of pulsars are analyzed. Comparison between theory and the observational data shows that two types of spectra for electron density fluctuations are realized in the interstellar medium: pure power law and piecewise with a break. The distribution of turbulent plasma in the Galaxy has a

Observations of the Local Interstellar Cloud [PDF]

open access: yesInternational Astronomical Union Colloquium, 1997
AbstractConstraints on the ambient (circumsolar) interstellar medium can be derived from observations of interstellar neutrals or their derivatives in the heliosphere. New results have been recently obtained which, when combined with optical and UV observations of the nearby stars (HST-GHRS, EUVE), remove long-standing contradictions and allow us to ...

Diffuse Interstellar Clouds [PDF]

open access: yesHighlights of Astronomy, 1992
AbstractDiffuse clouds are interstellar objects through which starlight is not greatly extinguished. As a result, many studies rely on ultraviolet and visible measurements. The focus of this review is on spectroscopic work involving atomic and molecular lines. From these measurements, the physical and chemical makeup of the clouds is derived.

Studying the depth of nearby interstellar clouds [PDF]

open access: yes, 2021
Molecular clouds are the birthplace of stars and planets. Understanding how stars are formed inside these interstellar clouds is one of the longest-standing questions in astronomy.

Chemical Composition of Interstellar Material

open access: yes, 1985
Abundances in Interstellar clouds, as determined from interstellar absorption lines, are discussed first, including abundances in ‘abnormal’ (high-velocity) clouds.
