Abstract:
Photoelectric photometry in the BV passbands is presented for 33
nearby RR Lyrae stars. CCD frames are used to recalibrate the
photographic photometry of an additional 7 RR Lyraes to the Johnson B
band. Light curves are presented for all 40 stars, along with derived
light curve parameters. For one subset of stars, reddenings and
distances are computed from the observed colors at minimum light,
periods, mean magnitudes, and spectroscopic metal abundances taken
from the literature. For a second subset of stars, metal abundances,
distances, and reddenings are determined via Fourier decomposition of
the light curves. The results of the two methods are compared.
