Table 8

Relative differences between the two stars deduced from our differential analysis, using the scaling relation for Δν.

dR/R ± σR = 0.009 ± 0.025
dM/M ± σM = 0.019 ± 0.072
Solar mixture GN93 AGS05
dt/t ± σdt −0.27 ± 0.29 −0.28 ± 0.31
dY0/Y0 ± σdY0 0.10 ± 0.21 0.13 ± 0.24

Notes. Radius and mass relative differences are obtained from Eqs. (7) and (8). Age and initial helium abundance relative differences are obtained from Eqs. (9) and (10).
