Descripción
The authors discuss two aspects related to the radial dependence of
spatial density of interplanetary dust. First, they ask which spatial
distribution the dust source should have to lead to the observed
relative spatial distribution. Sources limited to a shell at several AU
heliocentric distance are found to be inadequate, while extended (0.1 AU
≤ a ≤ 10 AU to 20 AU) sources with the semimajor axes distributed
≡a-1.0 or ≡a-1.1 reproduce the
observed density gradient. Second, the authors ask whether collisions in
interplanetary space would destroy enough of the larger meteoroid
particles to create a sufficient supply of dust-sized debris. This is
found to be the case. In addition, the extended dust source resulting
from these collisions approximately has the spatial distribution
required to fit the observed radial dependence of dust density. The
authors therefore consider radio and photographic meteoroids as the mass
reservoir from which the interplanetary dust cloud is maintained.
