Status of the Stardust ISPE and the Origin of Four Interstellar Dust Candidates [PDF]

, 2012
Some bulk properties of interstellar dust are known through infrared and X-ray observations of the interstellar medium. However, the properties of individual interstellar dust particles are largely unconstrained, so it is not known whether individual ...

Interstellar Dust Grain Alignment [PDF]

, 2018
Dust induced polarization is an efficient probe of the interstellar magnetic field. The combination of short wavelength dichroic extinction polarimetry with far-infrared/sub-mm wave emission observations, using modern instruments, allow us to measure the

Imprints of the Local Bubble and Dust Complexity on Polarized Dust Emission

The Astrophysical Journal
Using 3D dust maps and Planck polarized dust emission data, we investigate the influence of the 3D geometry of the nearby interstellar medium (ISM) on the statistics of the dust polarization on large ( $80^{\prime} $ ) scales.

Contactless Manipulation and Raman Analysis of Cometary Analogs and Micrometeorites by Acoustic Levitation

The Astrophysical Journal
Extraterrestrial material collected during space missions is highly exposed to contamination issues during on-Earth analysis. Although high-protection-level protocols were developed, to minimize the contamination due to sample manipulation and the ...

Mechanical Torque Disruption of Dust Grains Induced by Supernova Shock Waves

The Astrophysical Journal
The feedback from massive stars drives the evolution of interstellar dust grains by altering their physical properties via a number of radiative and mechanical processes.

Flux and composition of interstellar dust at Saturn from Cassini's Cosmic Dust Analyzer

, 2016
Interstellar dust (ISD) is the condensed phase of the interstellar medium. In situ data from the Cosmic Dust Analyzer on board the Cassini spacecraft reveal that the Saturnian system is passed by ISD grains from our immediate interstellar neighborhood ...

Extreme Starlight Polarization Efficiency toward ζ Ophiuchi: A Case for Line-of-sight Foreground Subtraction

The Astronomical Journal
Despite the pervasive nature of interstellar dust and its impact on nearly all observations, most dust corrections employ line-of-sight averages over large angular scales.

The role of dust in the interstellar medium: dust sources and dust evolution

, 2008
This contribution aims to give a brief overview of the nature of the dust in the interstellar medium, its rôle there, where it comes from, what happens to it while it resides there and what are some key outstanding dust issues that yet need further ...

Dust-extinction-curve Variation in the Translucent Interstellar Medium Is Driven by Polycyclic Aromatic Hydrocarbon Growth

The Astrophysical Journal Letters
The first all-sky, high-resolution, 3D map of the optical extinction curve of the Milky Way revealed an unexpected steepening of the extinction curve in the moderate-density, “translucent” interstellar medium (ISM).
