Derivation of invariant parameters for surface temperatures of airless bodyThermal inertia and thermal diffusivity are invariants of the one-dimensional heat equation with Stefan-Boltzmann Law boundary condition. Here, a formal derivation is given, along with a correction to the Standard Thermal Model for asteroids.
