Extreme Starlight Polarization Efficiency toward ζ Ophiuchi: A Case for Line-of-sight Foreground Subtraction

The Astronomical Journal
Despite the pervasive nature of interstellar dust and its impact on nearly all observations, most dust corrections employ line-of-sight averages over large angular scales.

A Catalog of Stellar and Dust Properties for 500,000 Stars in the Southwest Bar of the Small Magellanic Cloud

The Astrophysical Journal
We present a catalog of individual stellar and dust extinction properties along close to 500,000 sight lines in the southwest bar of the Small Magellanic Cloud (SMC). The catalog is based on multiband Hubble Space Telescope photometric data spanning near-

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

, 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.

Estimating Dust Attenuation from Galactic Spectra. III. Radial Variations of Dust Attenuation Scaling Relations in MaNGA Galaxies

The Astrophysical Journal
We investigate the radial dependence of the scaling relations of dust attenuation in nearby galaxies using integral field spectroscopy data from MaNGA.

The Spheroidal Analog Method for Modeling Irregular Porous Aggregates

The Astrophysical Journal
It is shown that the optical properties of an irregular porous grain with effective radius a _eff  ≲ 3 λ (where λ is the wavelength) can be well approximated by a “spheroidal analog”: a spheroid with appropriate axial ratio and size, with a dielectric ...

Dust in the small Magellanic cloud. 1: Interstellar polarization and extinction data [PDF]

, 1996
The typical extinction curve for the Small Magellanic Cloud (SMC), in contrast to that for the Galaxy, has no bump at 2175 A and has a steeper rise into the far ultraviolet.
