A process by which a homogeneous solution becomes crystal.
Noun from crystallize, → crystal.
Noun from bolur, from verb boluridan "to crystallize" + verbal noun suffix -eš.
white dwarf crystallization
bolureš-e sefid kutulé
Fr.: cristallisation de naine blanche
The most important phenomenon occurring during → white dwarf evolution, which results from its cooling. Crystallization is a → phase transition whereby → latent heat is released. At the cooler end of a white dwarf's life (→ cooling time), the → thermal energy of nuclei, which are positively charged ions, becomes small and the effects of electrostatic interaction on the motion of ions become important. The ions repel each other and their distribution will be such that the → Coulomb energy per ion is a minimum. This will cause the ions to form crystal-like lattice structures. As the star cystallizes it releases latent heat, providing an additional energy source that slows the cooling process compared to the → Mestel theory. Once the bulk of the white dwarf is crystalline, heat can travel through the star more easily and the white dwarf cools faster.
→ white; → dwarf; → crystallization.
