Abstract

A "liquid snowflake" or "Tyndall star" is a small, thin, star-shaped region of liquid water produced when ice is melted by absorption of light. In the early stages of its growth, the liquid inclusion appears as a small, approximately axially symmetric, lens-like object. We investigate some models, based on having a highly anisotropic kinetic-undercooling condition on the ice/water boundary, to try to understand the morphology of such a "Tyndall shape".
