What is it about?
Evaporation of minerals during planetary-system formation significantly affects the chemical characteristics of planetary materials. Many minerals are known to evaporate decomposing into multiple gas molecules without changing their original compositions (dissociative congruent evaporation). In this study, we have developed a new theory to describe the kinetics of such evaporation under non-equilibrium conditions.

Why is it important?
Our theory provides the first link between the experimental kinetic data and the mechanisms of dissociative congruent evaporation. This deepens our understanding of evaporation of minerals in space, which often proceeds under non-equilibrium conditions.
