Fig. 1.

Apsidal motion constant log k₂ (blue) and the inverse of mean mass density (cm³ g⁻¹, red) as a function of stellar mass. The models were computed using the MESA package. The corresponding log k₂ values were computed integrating the Radau differential equation using ZAMS (X_c = 0.696) non-rotating models.
