|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).
