Interstellar Carbon Dust

Journal of Carbon Research, 2019
In the ranking of cosmic abundance of the elements, carbon is the second element, after oxygen, able to form multiple bonds propagating the formation of a network, thus playing an essential role in the formation of nanometer- to micrometer-sized ...

Interstellar Dust in the Solar System

Astrophysics and Space Science, 1998
We 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 in the Solar System

Annual Review of Astronomy and Astrophysics, 2010
A fraction of the dust in the interstellar medium (ISM) enters the heliosphere and is measured in situ from spacecraft. This review surveys the in situ measurements and discusses a hence derived model of dust in the local interstellar cloud (LIC).

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. Before there were any measurements of the UV properties of interstellar extinction, interstellar particles were believed to be composed primarily of dirty ices.

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 ...

Influence of wall impacts on the Ulysses dust detector on understanding the interstellar dust flux

Planetary and Space Science, 2004
The Ulysses spacecraft orbits the Sun on a highly inclined orbit, and the impact ionization dust detector on board continuously measures interstellar dust grains with masses up to 10-13kg, penetrating deep into the Solar System.

Four interstellar dust candidates from the Stardust interstellar dust collector [PDF]

, 2011
In January 2006, the Stardust sample return capsule returned to Earth bearing the first solid samples from a primitive solar system body, Comet 81P/Wild2, and a collector dedicated to the capture and return of contemporary interstellar dust.

Physics of Interplanetary and Interstellar Dust

Space 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

Interstellar dust in the solar system

Earth, Moon, and Planets, 2004
Dust is an important component of galactic stucture and the cyclic processing of particulate matter leads to stellar and planetary formation. Though astronomical methods using analysis of dust-penetrating starlight can provide some limited information about the dust, the prospect of its in-situ sampling within the Solar System by spacecraft and its ...

From Interstellar Dust to Comets to Comet Dust: A Test of the Interstellar Dust Model of Comets

1991
The interstellar dust model of comets is used as a basis to simultaneously satisfy various observational constraints and to derive the porosity of comet dust. The observational constraints are: (1) the strengths of the 3.4 µm and 9.7 µm emission bands; (2) the shape of the 9.7 µm band; (3) the relative amount of silicates to organic materials; (4) the ...
