A detailed study of the reflection nebula, NGC 7023 [PDF]
, 1982 Polarisation and intensity maps in three broad wavebands are presented for the reflection nebula NGC7023. The data are used to investigate the structure, dust distribution and grain characteristics of the material surrounding the central illuminating ...

Infrared Spectroscopy of Interstellar Dust
, 2009 IR spectroscopy is the premier tool to study the composition of interstellar dust. Broad absorption and emission bands provide direct identification of the solid compounds present in space and allow measurement of accurate abundances. Systematic studies

Confined Chemistry in Space: Zeolite‐Supported Fe13 Nanoclusters Modulate CS Reactivity
Small Structures, Volume 7, Issue 3, March 2026.The study explores how an Fe13 cluster confined in chabazite reshapes the reaction of CS and H2 under astrochemical conditions. Confinement promotes C–S bond cleavage over hydrogenation, directing chemistry toward CH4 and H2S formation. Additional CS enables CS2 and C2 species. Microkinetic analysis identifies protoplanetary environments where zeolites

The Near-infrared Extinction Law at High and Low Galactic Latitudes
The Astrophysical JournalThe Milky Way dust extinction curve in the near-infrared (NIR) follows a power-law form, but the value of the slope, β _NIR , is debated. Systematic variations in the slope of the Milky Way UV extinction curve are known to be correlated with variations ...

Properties of interstellar dust [PDF]
Journal of Geophysical Research: Space Physics, 2000 The reference abundance of the interstellar medium (the abundance of elements in gas + dust), until recently assumed to be solar, is discussed because of its great importance for the composition of dust. For some important elements (O, N, and probably more), three lines of reasoning (observed gas‐phase abundances, H II regions, and stellar abundances ...

Small Structures, Volume 7, Issue 2, February 2026.This work describes how to conceive validated mixed machine learned/empirical energy functions based on finite‐sized molecular clusters for condensed phase simulations. Energy functions for pure and heterogeneous systems are one of the backbones for molecular simulation of condensed phase systems.

Properties of Interstellar Dust [PDF]
International Astronomical Union Colloquium, 1996 AbstractIn this review, the picture of the interstellar dust is outlined from the viewpoint of its role in galactic evolution. The modern concept of distinct dust populations is presented. The properties of the dust grains in the diffuse interstellar medium and in the molecular clouds are described.
