abstract: White Dwarfs in M4 and the Physics of Crystallization (D E. Winget1,2, S. O. Kepler2, Fabíola Campos2, M. H. Montgomery1,3) (1Department of Astronomy, University of Texas at Austin, Austin, TX, USA; 2Instituto de Física, Universidade Federal do Rio Grande do Sul, Porto Alegre, RS - Brasil 3 Delaware Asteroseismic Research Center, Mt. Cuba Observatory, Greenville, DE, USA) We explore the physics of crystallization in the dense Coulomb plasma of the deep interiors of white dwarf stars using the color-magnitude diagram and luminosity function constructed from Hubble Space Telescope photometry of the globular cluster M 4 and compare it with our results for proper motion cleaned Hubble Space Telescope photometry of the globular cluster NGC 6397. We demonstrate that the data are consistent with a binary mixture of carbon and oxygen crystallizing at a value of Gamma higher than the theoretical value for a One Component Plasma (OCP). We show that this result is in line with the latest Molecular Dynamics simulations for binary mixtures of C/O. We discuss implications for future work.
