Fig. 6.


Left: comparisons of projected rotational velocities (when known, see Table 2) to hardness ratios. Symbols are the same as in Fig. 2. Right: histogram of projected rotational velocities for all y Cas analogs (previously known ones and new ones) and stars without any y Cas characteristics but with similar effective temperatures (log(Teff) = 4.28 to 4.55).
