Two-Color Observations of RR Lyrae Stars in M14

Conference paper
Part of the Astrophysics and Space Science Library book series (ASSL, volume 36)

Abstract

Two-color photographic photometry has been carried out on RR Lyrae variables in M14. The position of these variables in the color-magnitude diagram is shown, and it is noted that there is a lack of horizontal branch stars to the red of the variable star gap. Color-amplitude, period-amplitude and color-period relations for the RR Lyrae variables measured are shown.
