Stellar parameters determined for ρ Oph A.

Teff [K] 22 000 ± 1000 M [M⊙] 12 + log(C ∕ H) 7.7 ± 0.2
log g [cgs] 4.0 ± 0.1 R [R⊙] 12 + log(N ∕ H) 7.5 ± 0.2
υmic [km s−1] 2 ± 1 τ [Myr] 12 + log(O ∕ H) 8.8 ± 0.2
υ sin i[km s−1] log L∕ L 12 + log(Si ∕ H) 7.6 ± 0.2
υmacro [km s−1] 12 + log(Mg ∕ H) 7.4 ± 0.2

Notes. Uncertainties are 1 σ-values. The υ sin i value is obtained from the analysis of the Si III 4567 Å line with the FT+GOF method in Simón-Díaz & Herrero (2014). The stellar parameters mass, radius, age, and luminosity are obtained with bonnsai (Schneider et al. 2014) adopting the evolutionarytracks by Brott et al. (2011).
