HR diagram of solar metallicity models without (dashed black line) and with rotation (solid coloured lines; here we show the fast rotators). The values of the surface velocity normalised to the break-up value (Ω/Ω_crit) increase from blue to red as shown on the right colour bar. The black triangles indicate when the rotating models are released from their disc. The red lines indicate the standard (dashed) and rotating (solid) ZAMS.
