The Evolution and Internal Structure of Neptunes and Sub-Neptunes: The importance of thermal conductivity in non-convective regions

[2509.04564] The Evolution and Internal Structure of Neptunes and Sub-Neptunes: The importance of thermal conductivity in non-convective regions Skip to main content We gratefully acknowledge support from the Simons Foundation, member institutions , and all contributors.
Such composition gradients can significantly affect the planetary thermal evolution.
We investigate how the evolution and internal structure of Neptunes and sub-Neptunes is affected when considering non-convective layers and the sensitivity of the results on the assumed thermal conductivity.
We find that the assumed conductivity significantly affects the planetary thermal evolution.
