Observing the structure of the interstellar clouds [PDF]

open access: yesJournal of Physics: Conference Series, 2005
We discuss some methods for characterizing the mass distribution in the interstellar clouds. This is done in the light of available observational techniques and of appropriate statistical tools capable to highlight the structural properties of the astronomical images.

Cosmic ray penetration in diffuse clouds [PDF]

open access: yes, 2015
Cosmic rays are a fundamental source of ionization for molecular and diffuse clouds, influencing their chemical, thermal, and dynamical evolution.

Measuring the fractal structure of interstellar clouds [PDF]

open access: yesSymposium - International Astronomical Union, 1991
To study the structure of interstellar clouds we used the so-called perimeter-area relation to estimate fractal dimensions. We studied the reliability of the method by applying it to artificial fractals and discuss some of the problems and pitfalls. Results for two different cloud types (high-velocity clouds (HVCs) and infrared cirrus) are summarized ...

Hierarchical structure of the interstellar molecular clouds and star formation

open access: yesOpen Astronomy, 2017
Properties of the hierarchical structures of interstellar molecular clouds are discussed. Particular attention is paid to the statistical correlations between velocity dispersion and size, and between the magnetic field strength and gas density.

CALCULATION OF CHEMICAL EQUILIBRIUM IN THE INTERSTELLAR CLOUD

open access: yesOdessa Astronomical Publications, 2017
In order to calculate the molecular concentrations in the interstellar cloud and to obtain heir spatial distribution we have made a computational code to solve the set of equations for chemical equilibrium and equations of charge and atom balance.

Two-component model of the interaction of an interstellar cloud with surrounding hot plasma

open access: yes, 2011
We present a two-component gasdynamic model of an interstellar cloud embedded in a hot plasma. It is assumed that the cloud consists of atomic hydrogen gas, interstellar plasma is quasineutral.

DESTRUCTION OF THE INTERSTELLAR CLOUDS BY THESHOCK WAVES

open access: yesOdessa Astronomical Publications, 2008
We study the influence of the interstellar cloud structure irregularity on the dynamics of its destruction by a supernova shock wave. It is shown that irregular clouds are destroyed twice quickly as the spherical ones.

Structure and evolution of interstellar carbonaceous dust. Insights from the laboratory

open access: yesFrontiers in Astronomy and Space Sciences, 2022
A large fraction of interstellar carbon is locked up in solid grains. The nature, origin and evolution of these grains have been investigated for decades.
