Extended Data Table 2 Derived stellar parameters for WR 46

From: Discovery of a transitional type of evolved massive star with a hard ionizing flux

  1. T2/3 and R2/3 denote the effective temperature and the corresponding radius at an optical depth of 2/3, applying the Stefan-Boltzmann law for the luminosity L. The surface abundances are given as mass fractions Xi for each element i. Given wind parameters are the mass-loss rate \(\dot{M}\), the transformed mass-loss rate \({\dot{M}}_{{\rm{t}}}\), the terminal wind velocity v and the mechanical luminosity \({L}_{{\rm{mech}}}=0.5\dot{M}{v}_{\infty }^{2}\). The assumed clumping parameters are D = 10 and vcl = 100 km/s.
