Abstract:
Simultaneous photometric (uvbyBeta) and spectrographic observations
of SX Phe are described. Analysis of the light and velocity frequency
spectra are performed. It is shown that all frequencies detected are
harmonics or combinations of the fundamental and first harmonic
frequencies. Intrinsic (b-y) and c1 values used in conjunction with
a model-atmosphere grid appropriate for a star with [M/H]=-1.0
yields <Teff≥7360K and =3.90. Standard evolutionary models
indicate the mass is 1.13 M☉ and <Mv> value is +2.9. The
radial-velocity data indicate a mean radial velocity of -37km/s
and a total range of 38km/s.
