The Evolution of the Planet: It Cools Down to Become a Class C.
The planets are very small, barren worlds full of volcanic activity. From their activity, carbon dioxide is trapped in the atmosphere and maintains temperatures at very high levels, regardless of location in the star system. When volcanic activity ceases, the planet "dies" and then transforms into a class C.
