[meteorite-list] Fireball Temperature?

[Meteorites USA]

Hi Laurence,

Thanks for the response! I'm humbled by your participation on this 
question... I appreciate it. I do have another question... ;) of course. 
Given the extreme temperature, and the massive pressure exerted on the 
meteoroid body while in it's incandescent state (ablation phase?), and 
taking into account the very short duration of this "meteor" state 
phenomena, would you agree that a 5-10 second "burn" would be sufficient 
enough to ablate 90% of a larger body's original mass? Assuming of 
course the body is an ordinary stone type meteoroid.

It just seems like such a very short period of time for something to 
sublimate into gases and physically ablate into such a small fraction of 
it's original mass.

Regards,
Eric
