Interstellar Dust
B. T. Draine
In the interstellar medium of the Milky Way, certain elements -- e.g., Mg, Si, Al, Ca, Ti, Fe -- reside predominantly in interstellar dust grains. These grains absorb, scatter, and…
Discrete-dipole approximation with polarizabilities that account for both finite wavelength and target geometry
Matthew J. Collinge, B. T. Draine
The discrete-dipole approximation (DDA) is a powerful method for calculating absorption and scattering by targets that have sizes smaller than or comparable to the wavelength of th…
X-ray Scattering Halos from the Galactic Center: Implications for Diffuse Emission Around SgrA*
Jonathan C. Tan, B. T. Draine
We consider the absorption and scattering of X-rays observed from the Galactic center. One objective is to characterize the intrinsic X-ray emission from the central black hole, Sg…
User Guide for the Discrete Dipole Approximation Code DDSCAT.6.0
B. T. Draine, P. J. Flatau
DDSCAT.6.0 is a freely available software package (http://www.astro.princeton.edu/~draine/DDSCAT.6.0.html) which applies the "discrete dipole approximation" (DDA) to calculate scat…
Scattering by Interstellar Dust Grains. II. X-Rays
B. T. Draine
Scattering and absorption of X-rays by interstellar dust is calculated for a model consisting of carbonaceous grains and amorphous silicate grains. The calculations employ realisti…
Interstellar Dust Grains
B. T. Draine
This review surveys the observed properties of interstellar dust grains: the wavelength-dependent extinction of starlight, including absorption features, from UV to IR; optical lum…
