Photoelectric Observations of RR Lyrae Stars.
Abstract
Photoelectric light-curves in yellow and blue for nine field RR Lyrae variables were obtained. Other photoelectric observations for fourteen more variables have been used to form relations between the subclasses of RR Lyrae stars. A correlation between the spectral appearance, color, and period for the RR Lyrae stars is shown. A correlation between the colors and metal abundances is suggested.
