Baade-Wesselink Distances to M5 and M92

Abstract

A Baade-Wesselink analysis has been performed using new optical and infrared photometry of four RR Lyrae variables in the globular cluster M5 and two in M92. We obtain a distance to M5 of 6.9 ± 0.45 kpc and to M92 of 7.85 ± 0.45 kpc, with a 0.3 kpc additional systematic uncertainty. These results are in excellent agreement with the previously published distances, based on matching the globular cluster main sequence to that defined by the field subdwarfs of known distance.
