This work presents new ab initio relativistic calculations using the multiconfiguration Dirac–Hartree–Fock method of some O i and O iii transition lines detected in B-type and Wolf–Rayet stars. Our results are the first able to be presented in both the length and velocity gauges, with excellent gauge convergence. Compared to previous experimental and theoretical uncertainties of up to 50 per cent,...
