The explanation behind this apparent paradox is that cool stars emit more longer-wavelength, near-infrared light, which is readily absorbed by a planet, heating it up. By comparison, hot stars emit more high-energy visible and UV light. If a planet is already icy, it will easily reflect these wavelengths, cooling the planet and leading to more ice, in a cycle called &#8220;ice-albedo feedback&#8221;.
