Stellar Evolution Model
A numerical simulation built on fluid dynamics, radiative transfer, and nuclear reaction networks, used to predict the process of stellar evolution, including the expansion behavior of red supergiants.

Possible reasons for the gap between model predictions and observational estimates include biases in how models handle mass loss rates, the limited ability of observational methods to detect extremely tenuous outer atmospheres, and real stars already self-limiting through violent mass ejection before expanding to extreme sizes.
The academic community generally believes that mass loss is one of the core factors explaining the gap between models and observations, but the quantitative details still await research.
