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-

IR emission and UV extinction in two open clusters [PDF]

Recent models of interstellar extinction have shown the importance of understanding both the UV and IR properties of interstellar dust grains. IRAS data have shown variations in 60 and 100 micron emissions presumably due to the presence of IR cirrus ...

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 ...

Investigation of [KSF2015] 1381-19L, a WC9-type Star in the High-extinction Galactic Region

The Astrophysical Journal
We report on a multiwavelength study of the Wolf–Rayet star [KSF2015] 1381-19L, which is located in the solar metallicity region ( Z = 0.014) of the Milky Way, strongly obscured by interstellar dust.
