Relationships between dust grain components responsible for observed interstellar extinction and polarization [PDF]

open access: yes, 1986
Ultraviolet extinction properties of interstellar dust are well observed. The amount of extinction measured in the visible (E(B-V)), at the 2200 A feature (E(BUMP)), and in the far ultraviolet (E(1550-V)) are only vaguely correlated indicating that at ...

Monitoring of the Interstellar Dust Stream in the Inner Solar System Using Data of Different Spacecraft [PDF]

open access: yes, 2004
Interstellar dust plays a key role in many astrophysical processes. However, until recently, astronomers could infer some properties of interstellar dust only through observations of starlight extinction and infrared emission.

Modeling Galactic Extinction with dust and "real" PAHs [PDF]

open access: yes, 2013
We elaborated an interstellar dust model assuming a distribution of core–mantle grains and a collection of single polyciclic aromatic hydrocarbons. Exploiting this model, we are able to reproduce a very large sample of galactic extinction profiles with

The End of the Road for Far-infrared Reddening Maps? Evidence for Reddening Errors Driven by Changes in Polycyclic Aromatic Hydrocarbon Abundance

open access: yesThe Astrophysical Journal
Accurate correction for extinction by Galactic dust is essential for studying the extragalactic sky. In the low-extinction regions of the Ursa Major molecular cloud complex, we demonstrate that Galactic dust reddening maps constructed from observations ...

Grain growth, optical polarisation, and extinction in interstellar clouds [PDF]

open access: yes, 1989
Increases in the wavelength of maximum polarization and the ratio of total to selective extinction are generally assumed to be the result of grain growth in interstellar clouds.

Large Variations Seen in First Ultraviolet Spectroscopic M33 Dust Extinction Curves

open access: yesThe Astrophysical Journal
Dust extinction curves provide one of the main avenues to understanding the detailed nature of dust grains and accounting for the effects of dust on observations of many astrophysical objects. For the first time, spectroscopic ultraviolet (UV) extinction

Large Interstellar Polarisation Survey

open access: yesAstronomy & Astrophysics
Our understanding of dust in the diffuse interstellar medium remains incomplete with regard to the structure, composition, size distribution, and alignment properties of its grains.

Microwave Extinction Measurements of Aerosolized Interstellar Dust Analogs [PDF]

open access: yes, 2016
Interstellar dust plays an important role in astrophysical processes and ob- servational astronomy, and a thorough knowledge of its composition and optical properties is essential to astronomy. However, only very limited intact samples of interstellar
