The formation of compact dusty clouds in diffuse interstellar medium (ISM) has been recently proposed and studied by Tsytovich et al. In the present paper, the effect of the clouds on the rate of H → H2 transition in the ISM is examined. We discuss the mechanisms leading to the formation of the clouds and the creation of gaseous clumps around them, analyze the main processes determining the efficiency of the recombination of atomic hydrogen on dust grains, and estimate the expected enhancement…

Optical properties and dust temperatures in clumpy diffuse medium

In this study, we explore the impact of inhomogeneities in the spatial distribution of interstellar dust on spatial scales of ≤1 au caused by ion shadowing forces on the optical properties of

Spatial distribution of dust density wave properties in fluid complex plasmas.

Complex plasmas consist of microparticles embedded in a low-temperature plasma and allow investigating various effects by tracing the motion of these microparticles. Dust density waves appear in

Impact of the Small-Scale Spatial Distribution of Dust Particles on the Chemical Evolution of the Diffuse Interstellar Medium

In this work we analyze the effect of gas-dust clumps, possibly formed in the interstellar medium due to instability, described in [10], on the chemical evolution of the diffuse interstellar medium.




A novel mechanism of the formation of compact dusty clouds in astrophysical environments is discussed. It is shown that the balance of collective forces operating in space dusty plasmas can result in

Interstellar clouds containing optically thin H2

Interstellar clouds containing optically thick H2 are investigated on the basis of the hypothesis that the population of the H2 rotational levels can be understood in terms of optical pumping in the

This paper presents a comprehensive analysis of the H2 formation process, under steady state conditions, using an exact solution of the master equation that provides an exact result for the hydrogen recombination rate and its dependence on the flux, the surface temperature, and the grain size.

H2 distribution during the formation of multiphase molecular clouds

Context. H2 is the simplest and the most abundant molecule in the interstellar medium (ISM), and its formation precedes the formation of other molecules. Aims. Understanding the dynamical influence

Parameterizing the interstellar dust temperature

The temperature of interstellar dust particles is of great importance to astronomers. It plays a crucial role in the thermodynamics of interstellar clouds, because of the gas-dust collisional

On the Role of Massive Stars in the Support and Destruction of Giant Molecular Clouds

We argue that massive stars are the dominant sources of energy for the turbulent motions within giant molecular clouds and that the primary agent of feedback is the expansion of H II regions within

Models of gas-grain chemistry in dense interstellar clouds with complex organic molecules

Models of the chemistry of dense interstellar clouds are presented in which both gas-phase and grain-surface chemistry occur. The dust grain and gas temperatures are fixed at 10 K, and the gas

[C II] absorption and emission in the diffuse interstellar medium across the Galactic plane

Aims. Ionized carbon is the main gas-phase reservoir of carbon in the neutral diffuse interstellar medium (ISM) and its 158 μm fine structure transition [C ii] is the most important cooling line of

Warm gas in the cold diffuse interstellar medium: Spectral signatures in the H 2 pure rotational lines

We present ISO-SWS observations of five pure rotational lines of H2 along a line of sight through the Galaxy which avoids regions of massive star formation. It samples 30 mag of gas, half of it (i.e.
