Evolutionary track of our model with M_ini = 294 M_⊙ and v_ini = 100 km s^-1 during core hydrogen burning in the HR diagram. Dots mark every 10⁵ years of evolution. The stellar wind mass-loss rate is colour coded; black dashed lines of constant radii are labelled according to their radius value. The star becomes a core-hydrogen-burning cool supergiant during the last 15% of its main-sequence evolution.
