This release introduces the evolutionary mass–radius models from Aguichine et al. (2025) and Tang et al. (2025).
These models are implemented as multidimensional grids with interpolation, allowing mass–radius relations to be explored as functions of planetary composition, equilibrium temperature, age, and host-star properties within their respective validity ranges.
The release includes model-specific configuration options, dedicated usage examples, and updated documentation describing their physical assumptions and recommended usage.
