The Journey of Interstellar Dust

, 2007
Interstellar dust particles undergo a complex journey in space. It commences with their formation in stellar outflows or outbursts, but may end in very different ways. Their fates range from sudden "death by destruction" promptly after their formation to

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

Effects of cosmic rays on hydrocarbon interstellar dust

, 2011
International audienceHydrogenated amorphous carbons, an important component of the interstellar carbonaceous dust, possess infrared spectral signatures (at 3.4, 6.9 and 7.3 µm) that are ubiquitous in the diffuse interstellar medium of galaxies, but not ...

Interstellar dust in the heliosphere [PDF]

, 1992
In the early 1990s, after its Jupiter flyby, the Ulysses spacecraft identified interstellar dust in the solar system. Since then the in-situ dust detector on board Ulysses continuously monitored interstellar grains with masses up to 10(-13) kg ...

Trapped Water on Silicates in the Laboratory and in Astrophysical Environments

The Astrophysical Journal
The existence of strongly bound water molecules on silicate surfaces, above the desorption temperature of water ice, was first predicted by computational studies and has recently been demonstrated by laboratory experiments.

Interrelationships between interstellar and interplanetary grains [PDF]

, 1986
The relationship between solar system dust (SSD) and interstellar dust particles (ISMD) is being reconsidered because of the discovery of isotopic anomalies in meteorites.

Mass-loss and silicate production in oxygen-rich AGB stars: current understanding and open questions

Frontiers in Astronomy and Space Sciences
AGB stars play a crucial role in the chemical enrichment of the Universe, polluting their host galaxies with gas and dust that reflect the nucleosynthesis processes active during their evolution.

Extreme-ultraviolet Photochemistry in Water-covered Carbonaceous Dust Analogs: Effects of Dust Thickness and Hydrogen Content

The Astrophysical Journal
Carbonaceous grains, as an abundant interstellar dust material, persist through several stages of the interstellar medium, providing a surface for gas-phase species condensation and chemical reactions.

The Evolution of Dust in the Multiphase Interstellar Medium

, 2002
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.

Stardust@home: A Massively Distributed Public Search for Interstellar Dust in the Stardust Interstellar Dust Collector [PDF]

, 2005
In January 2006, the Stardust mission will return the first samples from a solid solar system body beyond the Moon. Stardust was in the news in January 2004, when it encountered comet Wild2 and captured a sample of cometary dust.
