RE: (meteorobs) Excerpts from "CCNet 123/2001 - 22 November 2001"
Thanks for the various responses to my questions. While I personally doubt
the claim to a meteorite find in Indiana during the Leonid shower, I was
probing the possibility that such an occurrence was not completely out of
the realm of possibility. I notice no one addressed the hypothetical
question of whether a comet could sweep up material and later re-release it.
Seems plausible, at least to me.
OK, next line of questions. The geminids are not associated with a comet
but instead an asteroid. What produces the dust trail? There isn't a
(significant) vapor pressure from escaping gases to disburse particles, as
in a comet. I would guess that the particles' size distribution, and
density, would also be different. Is anyone trying to model the trail(s) in
the manner of the Leonid modeling?
Thanks again.

Naked eye Leonids appear to be composed of many grains held in a matrix by
various organic compounds. A 10kg bag's worth might just be more of the
same.
