Velocity distribution of O-type stars in the SMC. The plot shows the normalized observed v sin i distribution (blue) and the reconstructed initial rotational velocity (vrot, red) for 171 O-type stars. The dataset is a compilation from Ramachandran et al. (2019), Rickard et al. (2024), and Bestenlehner et al. (2025). About 10% of the O-type stars feature vrot > 450 km/s.
