The size of meteoroid constituent grains: Implications for interstellar meteoroids
2002The most widely accepted model for the structure of cometary meteoroids is a dustaball with grains bound together by a more volatile substance [1]. In this paper we estimate the size distribution of dustball grains from meteor flare duration, using image intensified CCD or 1998 Leonid meteors.

We have already mentioned repeatedly the great significance of the fragmentation of meteoroids (see Sections 20, 31, and 34). Now let us consider the main observational data attesting to this phenomenon [194]: (1) a high rate of ablation and, as a result, shorter trajectories and higher fadeout altitudes than are to be expected from the ...

Probability of meteoroidal penetration
AIAA Journal, 1964The past technique of calculating the flux of meteoroids capable of penetrating the skin of a spaceship is critically reviewed A new, more rigorous technique, compatible with any assumed meteoroidal flux, velocity distribution, and penetration equation, is derived using integral calculus Several values of a constant convenient for calculating the ...

Ablation is defined as a removal of meteoroid mass via phase transformations of the solid surface layer to the liquid or gaseous state. Ablation involves: (a) fusion of the outer layer, followed by spraying of the liquid layer by the oncoming air flow; (b) vaporization of the solid phase or liquid layer, and removal of mass in the ...

The formation of meteoroid streams, the forces affecting their subsequent motion and the techniques used in order to understand their dynamical evolution are discussed. One example of Chaotic motion is given in the final section.
