Interstellar dust and extinction

Annual Review of Astronomy and Astrophysics, 1987
The 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.

Lagrangian fluid approach for the modeling of peculiarities of the interstellar dust distribution in the astrospheres/heliosphere

, 2019
Interstellar dust penetrates into the heliosphere/astrosphere due to relative motion of the Sun and the local interstellar medium (LISM). Inside the heliosphere/astrosphere and at the heliospheric boundaries, where the solar/stellar wind interacts with

Interstellar Dust Clouds

Nature, 1971
THE failure, thus far, to detect gaseous emission lines from circumstellar dust clouds1–3 and from Bok globules2 raises the possibility that such clouds consist solely of dust grains. The possibility has previously been largely discounted on the grounds that relative diffusion of the grains and gas is slow and inefficient requiring time scales which ...

The Composition of Interstellar Dust [PDF]

open access: possible, 1996
The majority of interstellar grain models are based on a dust population composed of carbon and silicate grains. Abundance studies using high-resolution absorption line spectra, however, suggest that other grain types, perhaps oxides or metal grains, are prevalent in interstellar clouds.

Physics of Interplanetary and Interstellar Dust [PDF]

open access: possibleSpace Science Reviews, 1996
Observations of dust in the solar system and in the diffuse interstellar medium are summarized. New measurements of interstellar dust in the heliosphere extend our knowledge about micron-sized and bigger particles in the local interstellar medium. Interplanetary grains extend from submicron- to meter-sized meteoroids. The main destructive effect in the

Dust in the Interstellar Medium [PDF]

open access: possible, 2007
The study of interstellar dust is an essential aspect of fundamental astrophysical problems, including the evolution of galaxies, the formation of stars, the building of planets and, possibly, the synthesis of organic molecules which lead to life. The life cycle of dust is associated with that of the stars.

Interstellar Dust Grain Alignment

, 2015
Interstellar polarization at optical-to-infrared wavelengths is known to arise from asymmetric dust grains aligned with the magnetic field. This effect provides a potentially powerful probe of magnetic field structure and strength if the details of the ...

Interstellar Dust and Diamonds

Nature, 1969
Saslaw and Gaustad1 have recently suggested that interstellar dust may consist of small diamond particles. This suggestion can be verified if the optical properties of such particles can be determined. The optical constants of bulk diamond have been measured by Phillipp and Taft2 over the entire waveband of astronomical interest, ∼2 micron–1000 A.

Evolution of Interstellar Dust

1987
This paper presents a review of our current knowledge of interstellar dust. The composition of the interstellar dust is summarized in Table 1. About half of the dust volume consists of amorphous silicates. The other half has to be made up out of a carbonaceous component, such as graphite, amorphous carbon (e.g., soot), and/or organic grain mantles (e.g.
