Abstract:
BV photometry is presented for 12 RR Lyr variables discovered in the
presumably young galactic globular cluster Ruprecht 106. All variables
are type RRab, and their periods span a narrow range from 0.574 to
0.652 day. We report also on the discovery of three SX Phe variables
among the cluster blue stragglers. A likely background RR Lyr variable
and two foreground contact binaries were also found in the cluster
field. The reddening of Ruprecht 106 is estimated at E(B-V)=0.20 based
on the (B-V) colors exhibited by the cluster RR Lyr variables at
minimum light. Analysis of the period vs amplitude and period vs
rise-time diagrams suggests similar metallicities of Ruprecht 106 and
M3. A peak (or bump) is present in the luminosity function of the red
giant branch of Ru 106. Its position relative to the horizontal branch
is consistent with a cluster metallicity of [Fe/H]>=-1.6.
