Luminosities of SX Phoenicis, large-amplitude delta Scut, and RR Lyrae stars.

McNAMARA D.H.

Abstract (from CDS):

begin{tex}Str1mgren _uvbyβphotometry of SX Phoenicis and large-amplitude δScuti variables is analyzed to determine the mean temperatures, metal abundances, and surface gravities of the stars. The mean temperatures and fundamental periods are used in conjunction with the pulsation equation and stellar models to derive masses, radii, surface gravities, and M_bol of the variables. The stars exhibit a period-luminosity relation. With the aid of Hipparcos trigonometric parallaxes the zero-point of the M_v, p is set. We find M_v = -3.725 log P - 1.933. This P-L relation is utilized to find the M-v values of RR Lyrae stars or horizontal-branch stars in globular clusters and the Carina galaxy-objects that contain both SX Phe, and RR Lyrae variables, or horizontal-branch stars. The M_v values of the metal-ppor RR Lyrae stars are found to be consistent with M_v [Fe/H] calibrations derived by Sandage (1993) and by McNamara (1997) from revised Baade- Wesselink M_v values. At [Fe/H] = -1.9 M_v is 0.42. Feast and Catchpole (1997) suggestion that M_v = 0.25 at [Fe/H] = -1.9 for RR Lyrae is discussed. This M_v vlue is too luminous because it makes the (T_eff) of RR Lyraes too high-well off any (T_eff) = _f (color index)
