Simulated tail of corundum meta-particles viewed from above the orbital plane (left panel) and in the orbital plane (right panel) with meta-particles colour coded according to meta-particle radius. The axes of the left panel have the same scale; however, the vertical axis of the right panel is stretched by a factor of ~1000 relative to the horizontal axis because the tail is much longer than it is high. These meta-particles have an initial radius of 1 μm and were ejected from a planet of mass 0.02 M_⊕ and radius 0.28 R_⊕ in a continuous and spherically symmetric distribution with a velocity of 1.034 surface escape velocities (or 3.13 km s⁻¹). The meta-particles were tracked as they sublimated until they were removed when they reached a radius of 1 nm. The sublimation rate of the meta-particles was set so that they reached a radius of 1 nm after one planetary orbit.
