Composition, structure and chemistry of interstellar dust
The observational constraints on the composition of the interstellar dust are analyzed. The dust in the diffuse interstellar medium consists of a mixture of stardust (amorphous silicates, amorphous carbon, polycyclic aromatic hydrocarbons, and graphite ...

Interrelationships between interstellar and interplanetary grains
The relationship between solar system dust (SSD) and interstellar dust particles (ISMD) is being reconsidered because of the discovery of isotopic anomalies in meteorites.

Interstellar dust: insights from depletion and diffuse interstellar bands (DIBs)
openLa polvere interstellare rappresenta una frontiera ancora oscura nello studio del cosmo, costituendo una componente fondamentale del mezzo interstellare per effetti di estinzione della luce e studio delle abbondanze chimiche nelle galassie. In questa

The Evolution of Dust in the Multiphase Interstellar Medium
Interstellar dust has a profound effect on the structure and evolution of the interstellar medium (ISM) and on the processes by which stars form from it.

We discuss the inherent difficulties that arise during "ground truth" characterization of the Stardust interstellar dust collector. The challenge of identifying contemporary interstellar dust impact tracks in aerogel is described within the context of ...

Interstellar Dust in the Solar System
Astrophysics and Space Science, 1998We deduce the mass distribution and total mass density of interstellar dust streaming into the solar system and compare the results to the conditions of the very local interstellar medium (VLISM). The mass distribution derived from in situ measurements shows a gentler slope and includes larger grains, compared to a model distribution proposed for the ...

Interstellar Dust and Extinction
Annual Review of Astronomy and Astrophysics, 1987The ultraviolet (UV) region of the spectrum has been crucial in providing information on the nature of the material and size distribution of the particles of interstellar dust. Before there were any measurements of the UV properties of interstellar extinction, interstellar particles were believed to be composed primarily of dirty ices.
