Long-wavelength absorption by fractal dust grains
E. L. Wright;
ApJ, 1987, 320, 818
ABSTRACT:The far-infrared and submillimeter absorption properties of random aggregates of conducting spheres have been studied as a possible source for the
long-wavelength absorption of interstellar dust grains.
The complex shapes of random
aggregates have various fractal dimensions, depending on the process that forms
them.
The long wavelength absorption versus frequency is affected more by the
shape of a conducting grain than by its composition.
