A Mechanism of Crystallization of Cometary Silicates

We propose a new mechanism of crystallization of cometary silicate. The crystallization is due to heat released by chemical reactions in the organic refractory mantle of Greenberg’s model of cometary dust induced by moderate heating by solar radiation. It is shown that the strength of the crystallin...

Description
Summary:We propose a new mechanism of crystallization of cometary silicate. The crystallization is due to heat released by chemical reactions in the organic refractory mantle of Greenberg’s model of cometary dust induced by moderate heating by solar radiation. It is shown that the strength of the crystalline feature observed in the comets can be reproduced by the present mechanism of crystallization.
