Recent publications have discussed the existence of stable B stars in the β CMa instability strip of the (β, Q) plane (Lesh and Aizenman, 1973) and the (log g, θe) and (Mbol, log Te) planes (Watson, 1972). The new lists of Strömgren uvbyβ photometry published by Crawford et al. (1970, 1971a, 1971b) for most of the B stars in the Bright Star Catalogue suggested that one might determine quite precisely the proportion of stable B stars (that is, stars not known as β CMa variables) in a luminosity/colour plot in the form of the β index against [c1] = c1 −0.2 (b – y).
