[Fe/H] relations for c-type RR Lyrae variables based upon Fourier coefficients.

MORGAN S.M., WAHL J.N. and WIECKHORST R.M.

Abstract (from CDS):

[Fe/H]-φ31-P relations are found for c-type RR Lyrae stars in globular clusters. The relations are analogous to that found by Jurcsik & Kovács for field ab-type RR Lyrae stars, where a longer period correlates with lower metallicity values for similar values of the Fourier coefficient φ31. The relations obtained here are used to determine the metallicity of field c-type RR Lyrae stars, those within ωCen, the Large Magellanic Cloud and toward the galactic bulge. The results are found to compare favourably to metallicity values obtained elsewhere.
