All Tables

Table 1: Main parameters of the pulsation models used in this paper.
Table 2: Selected results of SHB simulations with $Z\le$ 0.006. For each metal content Zand mean mass of HB stars M(HB), we list the predicted mean values of the HB type and of the RR Lyrae mass, absolute magnitude and $k_{\rm ev}$ parameters, together with the rms dispersion about the mean. The masses are in solar units.
Table 3: Selected parameters for Galactic globular clusters: HB type, average period of ab-type RR Lyrae stars and iron-to-hydrogen content [Fe/H]_K according to the Kraft & Ivans (2003) metallicity scale. For $\omega$ Cen, we list the average [Fe/H]_R value from Rey et al. (2000) data.
Table 4: Mean $k(1.5)_{\rm puls}$ and $k(2.0)_{\rm puls}$ values for RR_ab stars in Galactic globular clusters.
Table 5: Average mass M(RR) of RR_ab stars in Galactic globular clusters inferred by SHB computations, adopting solar-scaled chemical compositions and $(Z/X)_{\odot }=0.0245$ . These masses are used with Eqs. (2) and (3) to estimate the visual distance moduli $\langle \mu_V\rangle$ and the mean absolute magnitudes $\langle M_V\rangle$ listed in Cols. (5)-(8).
Table 6: Selected results of SHB simulations with $Z\ge 0.002$ . For each given metal abundance, we list the mean mass of HB stars producing very blue and very red HB types and the corresponding mean mass of RR Lyrae stars. The last column gives the average mass (logarithm) of the predicted RR Lyrae stars for the whole range from HB = +0.95 to HB = -0.95. All the mass values hold for old stellar structures (see text).
