Fig. 1: Comparing the distributions of BSS rotational velocities.

From: Fast rotating blue stragglers prefer loose clusters

Fig. 1

a Kernel-density distributions of the rotational velocities measured for 320 BSSs in the eight surveyed GCs (top panel), compared with that obtained for a sample of 216 RGB, SGB and MSTO stars (bottom panel). Both distributions are normalised to the total number of stars observed in each sample. b Kernel-density distributions of the BSS rotational velocities observed in each of the eight clusters, normalised to the total number of BSSs observed in every system.
