Unusual relative strengths of the diffuse interstellar bands in some interstellar dust clouds [PDF]

open access: yes, 1986
Some of the diffuse interstellar features (DIBs) in the spectra of certain stars at high galactic latitudes (1 is greater than 15 degrees) are unusually weak or absent while others have the strength expected for their color excess.

Ultraviolet Interstellar Extinction toward High Galactic Latitudes

open access: yesThe Astrophysical Journal
Nearby high Galactic latitude clouds provide a unique laboratory to study the physics and structure of the Galactic interstellar medium and the properties of the interstellar dust.

Radiative transfer and chemistry in spheroidal interstellar clouds

open access: yes, 2002
The thesis begins by describing the way in which gas phase chemistry of the interstellar medium can be modelled, and demonstrating the potential significance of chemical reactions on the surfaces of dust grains present in the gas. The dust also serves as

A Pan-galaxy Study of Synthetic Giant Molecular Filaments: A Turbulence-dominated Life Cycle

open access: yesThe Astrophysical Journal Supplement Series
Recent surveys of the Galactic plane have revealed dozens of giant molecular filaments (GMFs), with lengths ranging from tens to hundreds of parsecs, yet their origins and life cycles remain debated. In this work, we analyze over 700 GMFs identified from

Does the H+5 hydrogen cluster exist in dense interstellar clouds?

open access: yes, 2012
The clustering of hydrogen molecules around a cation in dense interstellar clouds is examined taking into account recent accurate information about the structure and thermochemistry of these clusters.

The Young Ages of 70 μm Dark Clumps Inferred from Carbon Chain Chemistry

open access: yesThe Astrophysical Journal
The physical conditions of the earliest environment of high-mass star formation are currently poorly understood. To that end, we present observations of the carbon chain molecules HC _5 N, CCS, and HC _7 N in the 22–25 GHz band toward 12 high-mass 70 μ m

Non-equilibrium ionization around clouds evaporating in the interstellar medium [PDF]

open access: yes, 1986
It is of prime importance for global models of the interstellar medium to know whether dense clouds do or do not evaporate in the hot coronal gas. The rate of mass exchanges between phases depends very much on that.
