Abstract:
We present for the first time optical (V, I and Gunn z) colour
magnitude diagrams for Terzan 6, which were collected under excellent
seeing conditions with the ESO NTT telescope. The horizontal branch
morphology is red, nearly superimposed on the red giant branch. The
red giant branch morphology presents characteristics intermediate
between those of 47 Tuc and NGC 6528/NGC 6553. We derive a reddening
of E(B-V)=2.24 and a distance d☉=7.0kpc (assuming R=3.1). We
conclude that Terzan 6 belongs to the metal-rich bulge globular
cluster system.
