Interstellar Dust

, 2003
In the interstellar medium of the Milky Way, certain elements -- e.g., Mg, Si, Al, Ca, Ti, Fe -- reside predominantly in interstellar dust grains. These grains absorb, scatter, and emit electromagnetic radiation, heat the interstellar medium by photoelectric emission, play a role in the ionization balance of the gas, and catalyze the formation of ...

Techniques for Galactic Dust Measurements in the Heliosphere [PDF]

, 1999
Galactic interstellar dust (ISD) is the major ingredient in planetary formation. However, information on this important material has been extremely limited.

One Relation for All Wavelengths: The Far-ultraviolet to Mid-infrared Milky Way Spectroscopic R(V)-dependent Dust Extinction Relationship

The Astrophysical Journal, 2023
Dust extinction is one of the fundamental measurements of dust grain sizes, compositions, and shapes. Most of the wavelength-dependent variations seen in Milky Way extinction are strongly correlated with the single parameter R ( V ) = A ( V )/ E ( B − V )

Aspects of the Mass Distribution of Interstellar Dust Grains in the Solar System from In-Situ Measurements [PDF]

, 1999
The in-situ detection of interstellar dust grains in the Solar System by the dust instruments on-board the Ulysses and Galileo spacecraft as well as the recent measurements of hyperbolic radar meteors give information on the properties of the ...

Dust in protoplanetary disks: observations*

EPJ Web of Conferences, 2015
Solid particles, usually referred to as dust, are a crucial component of interstellar matter and of planet forming disks surrounding young stars. Despite the relatively small mass fraction of ≈1% (in the solar neighborhood of our galaxy; this number may ...

Interstellar Dust Close to the Sun [PDF]

, 2012
The low density interstellar medium (ISM) close to the Sun and inside of the heliosphere provides a unique laboratory for studying interstellar dust grains.

The nature of interstellar dust as revealed by light scattering

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2011
Interstellar dust was first identified through the extinction that it causes of optical starlight. Initially, observational and theoretical studies of extinction were made to identify simple ways of removing the effect of extinction.

Interstellar Dust in the Solar System: Model versus In-Situ Spacecraft Data

, 2019
In the early 1990s, contemporary interstellar dust penetrating deep into the heliosphere was identified with the in-situ dust detector on board the Ulysses spacecraft.

X-ray Halos and Large Grains in the Diffuse Interstellar Medium [PDF]

, 2001
Recent observations with dust detectors on board the interplanetary spacecraft Ulysses and Galileo have recorded a substantial flux of large interstellar grains with radii between 0.25 and 2.0 mu entering the solar system from the local interstellar ...
