The distance to IC 4499 from K-band photometry of 32 RR Lyrae stars.

STORM J.

Abstract (from CDS):

Single epoch K-band photometry of 32 RR Lyrae stars in the young galactic globular cluster IC 4499 is presented. The mean magnitudes have been estimated using the K-band template light-curves of Jones et al. (1996PASP..108..877J ). We derive an independent estimate of the distance and reddening for the cluster based on the new <MK>-logP-[Fe/H] relation from Bono et al. (2003MNRAS.344.1097B) which has a zero-point in agreement with the canonical LMC distance of (m-M)0=18.5. For an assumed metallicity of [Fe/H]=-1.65±0.1 we find (m-M)0=16.47±0.04±0.06 (random and systematic errors respectively) and E(B-V)=0.24±0.03 in good agreement with the findings of Walker & Nemec (1996AJ....112.2026W) based on optical data. The distance estimate is very robust to uncertainties in the reddening estimate but naturally depends directly on the adopted zero-point of the <MK>-logP-[Fe/H] relation.
