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 ...

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

Dust Environment Model of the Interstellar Comet 2I/Borisov

Astrophysical Journal, 2020
2I/Borisov is the first interstellar comet discovered on 2019 August 30, and it soon showed a coma and a dust tail. This study reports the results of images obtained at the Telescopio Nazionale Galileo telescope, on La Palma—Canary Islands, in 2019 ...

Interstellar carbon dust

SCIENTIA SINICA Physica, Mechanica & Astronomica, 2017
Carbon is the fourth most abundant element in the Universe after hydrogen, helium and oxygen. Synthesized at the late evolutionary stage of stars, carbon is ejected from stars through mass loss of asymptotic giant branch stars and explosion of supernovae and then enters the interstellar medium in the form of ions, atoms, molecules and solid dust ...

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 models

Advances in Space Research, 1993
Abstract Interstellar dust models, previously constrained only from the extinction curve, have been radically changed with the arrival of IRAS observations of the dust infrared emission. An important component of interstellar dust is likely to be made of small particles that show a fluctuating temperature upon impinging single photons and which can ...

Dust - Interplanetary And Interstellar

1973
In the physical universe, perturbative clumpings of material include the entire spectrum of sizes from the subatomic to the metagalaxy. The span of masses from the electron to our Galaxy goes from 10-27 to 1044 gm, or 71 powers of 10. Between these two extremes, Nature displays a comprehensive array to the astronomer, as listed in Table 6-I.

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.

Interstellar Dust Grains

2012
This chapter discusses the interstellar grains, including the effects of extinction, polarization, and energy emission in the infrared spectrum. An overview of Mie’s theory is given, and the chapter ends with a discussion of the physical properties of the interstellar grains.

Interstellar Dust and Circumstellar Dust Disks

2001
Interstellar dust research belongs to the young branches of astrophysics. With the establishment of sensitive observational techniques in the astronomical infrared spectroscopy in the 1960s, diagnostic circumstellar and interstellar dust bands were detected and induced an explosive development of the whole field.
