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 ...

On the Nature of Interstellar Grains [PDF]

, 2015
Whether through absorption, scattering, or emission, the effects of interstellar dust are manifest at nearly all wavelengths of astronomical interest. This dissertation synthesizes observations of the diverse optical phenomenology of interstellar dust to

Dust in the small Magellanic Cloud. 2: Dust models from interstellar polarization and extinction data [PDF]

, 1995
We study the dust in the Small Magellanic Cloud using our polarization and extinction data (Paper 1) and existing dust models. The data suggest that the monotonic SMC extinction curve is related to values of lambda(sub max), the wavelength of maximum ...
