NEW ULTRAVIOLET EXTINCTION CURVES FOR INTERSTELLAR DUST IN M31 [PDF]
The Astrophysical Journal, 2015 New low-resolution UV spectra of a sample of reddened OB stars in M31 were obtained with HST/STIS to study the wavelength dependence of interstellar extinction and the nature of the underlying dust grain populations.

Interstellar Dust Models Consistent with Extinction, Emission, and Abundance Constraints [PDF]
The Astrophysical Journal Supplement Series, 2004 We present new interstellar dust models which have been derived by simultaneously fitting the far-ultraviolet to near-infrared extinction, the diffuse infrared (IR) emission and, unlike previous models, the elemental abundance constraints on the dust for

A First Taste of MEAD (Measuring Extinction and Abundances of Dust). I. Diffuse Milky Way Interstellar Dust Extinction Features in JWST Infrared Spectra [PDF]
The Astronomical JournalWe present the initial results of the Measuring Extinction and Abundances of Dust project, with a focus on the dust extinction features observed in our JWST near- and mid-infrared spectra of nine diffuse Milky Way sightlines (1.2 ≤ A ( V ) ≤ 2.5).

Dust Plasma Analogue for Interstellar 217.5 nm Extinction [PDF]
Serbian Astronomical Journal, 2008 The new ultraviolet (UV) extinction measurements of carbonaceous nanoparticles in the range from 140 nm to 260 nm are presented. The plasma polymerized hydrocarbon nanoparticles were already proposed as a new astro analogue, which describe the infrared (

DIBs, Interstellar Dust, and Extinction [PDF]
Proceedings of the International Astronomical Union, 2013 AbstractThe relationship between DIBs and dust is still unknown. The correlation between reddening and DIB strength means that the DIBs are mixed in with the dust and gas in interstellar clouds. The DIBs are relatively stronger in the diffuse interstellar medium than in dense clouds.

Dust in the Small Magellanic Cloud: Interstellar Polarization and Extinction [PDF]
The Astrophysical Journal, 1997 To elucidate the dust properties in the SMC we have for the first time measured linear polarization in five colors in the optical region of the spectrum for a sample of reddened stars. For two of these stars, for which there were no existing UV spectrophotometric measurements, but for which we measured a relatively large polarization, we have also ...

INTERSTELLAR EXTINCTION MODELLING BY AGGREGATE DUST
International Journal of Advanced ResearchExtinction generally ours whenever electromagnetic radiation propagates through a medium containing small particles. The spectral dependence of extinction, or extinction curve, is a function of the composition, structure and size distribution of the particles.
