CRYSTALLIZED STARS. Scientists have previously thought that as white dwarf stars assumed their final repose, a wave of crystallization would propagate outward from the interior, freezing nuclei into a lattice. Gilles Chabrier (Ecole Normale Superieure de Lyon, France), Neal W. Ashcroft (Cornell), and Hugh E. DeWitt (Livermore) believe that such an ensemble of particles cannot be treated classically (as was the case) but must be considered as a quantum liquid freezing into a quantum solid. The result of their re-evaluation would be to lower the freezing temperature of heavier white dwarfs and to slow their cooling and evolution. This in turn would have implications for studies of the galactic disk and halo. (Nature, 5 Nov. 1992.)
