Astronomy

Thermal Evolution of Carbon-Rich Exoplanets and Diamond Layers

Quick fact

Some carbon-rich exoplanets, like 55 Cancri e, could have mantles up to one-third diamond by volume, and the high thermal conductivity of diamond means heat escapes much faster than through Earth's rocky mantle, dramatically altering the planet's cooling history.

Why this is interesting

Imagine an entire planet where the mantle is made of diamonds—not rock. How would that change the way the planet cools and evolves?
