We simulate the formation of these gravitational molecules, determine their co-moving regions, and compute ionization fluxes induced by orbital motion for various binary eccentricities. We develop semi-analytic formalisms to describe the ionization dynamics of both the co-moving and non-co-moving regions, demonstrating consistency with numerical simulation results.
