Radius, luminosity, and mass versus Teff for the stars in NGC 6752 (left panels) and ω Cen (right panels). Teff here is obtained from the SED fit. The two variables (asterisks) and three BSSs (triangles) in NGC 6752 are marked. The filled symbols in ω Cen indicate the He-rich (blue-hook) stars. We show the theoretical ZAHB and TAHB for He-normal (solid) and He-enriched (dashed) models.
