Stothers, R., 1981: RR Lyrae stars: A theoretical study of Bailey types a and b. Astrophys. J., 247, 941-948, doi:10.1086/159103.

The full-amplitude behaviour of theoretical model of RR Lyr stars pulsating in the fundamental mode has been explored with the use of Carson's radiative opacities. A detailed comparison of the models with metal-poor RR Lyr stars of Bailey types a and b suggests that these stars have properties that lie somewhere in the following range: M/M = 0.55-0.65, Y = 0.2-0.3, and log (L/L) = 1.6-1.7. In obtaining these results, the only data that are used are velocity curves and light curves. Independent information, however, seems to corroborate the values found here. The use of Los Alamos opacities gives somewhat similar results, although the derived masses are smaller by about 20%.
