The RR Lyrae Luminosity Metallicity Relation Revisited
We utilize a set of internally consistent absolute ages for a sample of ten Galactic globular clusters to determine the variation of the slope with the zero point of the M _V (RR) ∼ [Fe/H] relation for RR Lyrae variables. Our formalism relies on numerical modeling of the main sequence turnoff magnit...
