Chemical surface abundances of the primary and secondary stars of HD 17505Aa.

Primary Secondary Sun
He/H 0.1 (fixed) 0.1 (fixed) 0.089
C/H 2.69 × 10−4
N/H 6.76 × 10−5
O/H 4.90 × 10−4

Notes. Abundances are given bynumber as obtained with CMFGEN. The solar abundances (Asplund et al. 2009) are quoted in the last column. The 1σ uncertainty corresponds to abundances that yield a normalized χ2 of 2.0 (Martins et al. 2015). The values of the He abundances have been fixed in the models.
