Re: (meteorobs) P/2000 G1 & Vgeo
Hi!
The thermal conductivity of the meteoroid would most probably depend
on the material. Iron meteoroides probably have high thermal conductivity
since they are made of metals. But stony meteoroids and cometary snow
flakes have lower thermal conductivity than iron meteoroids, so they will
obviously behave in a different way.
The thermal conductivity, given a constant meteoroid size for all
materials,
will then determine how much time is required for the meteoroid to reach
its
boiling point.
For a given size the maximum luminosity will be reached by the cometary
meteoroid. Then come iron and stony meteoroids. Is there a connection
between the thermal conductivity of a meteoroid - the rate at which the
material
will absorb the thermal energy and the luminosity of the meteor?
Perhaps the iron meteoroids produce less luminous meteors because they
absorb the thermal energy of the ionized gas that envelops them quicker
than
cometary meteoroids, thus reducing the amount of ionization and thus the
luminosity?
Man, I'm waaay off, and probably way off truth as well.
Clear skies!
