Re: (meteorobs) Re: Meteoroid Size

Oops - this is what I get for dashing off a reply...

I wrote:

"older populations will lose their less dense members fairly rapidly"

I meant:

Older streams that are not replenished regularly by the parent comet will
have long since lost their less-dense members due to the Poynting-Robertson

The articles I referenced included:

Brown, P & Jones, J (1998) Simulation of the Formation and Evolution of the
Perseid Meteor Stream.  Icarus, V. 133, Issue 1, pp. 36-68

Bibarsov, R, Narziev, M & Chebotarev, R (1990) Determination of the masses
and densities of meteoroids according to radar observations from a single
station.  Astronomicheskii Vestnik, V. 24, Oct-Dec 1990, p. 326-332

Babadzhanov, P & Makhmudov, N (1992) Density of the Taurid meteoroids
according to photographic observations.  Akademiia Nauk Respubliki
Tadzhikistan, Doklady, V. 35, no. 1, p. 16-19

And lastly, even my old stand by, Abell (1964) mentions that some
meteoroids "may have densities much less than that of water".
