Segue 3 VI photometry
Listed in IVOA Registry (Virtual Observatory)
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.
Description
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. (2011AJ....142...88F, Cat.
J/AJ/142/88). 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_{sun}_=29.1kpc is compatible with the outer halo location of other low luminosity globular clusters.
