Segue 3: the youngest globular cluster in the outer halo.

ORTOLANI S., BICA E. and BARBUY B.

Abstract (from CDS):

Deep Galileo (Telescopio Nazionale Galileo) B, V and I images of Segue 3, reaching V ∼ 25, reveal that it is the youngest globular cluster known so far in the Galaxy. A young age of 3.2Gyr is found, differently from a previous estimate of 12Gyr. It also appears to be moderately metal rich with [Fe/H] ∼ -0.8, rather than [Fe/H] ∼ -1.7, as previously suggested by Fadely et al. A main difference in the age derivation relative to Fadely et al. comes from the consideration of subgiant branch stars in the isochrone fitting. A deduced distance of d☉ = 29.1kpc is compatible with the outer halo location of other low luminosity globular clusters.
