We have been investigating the metallicity dependence of star and planet formation, particularly focusing on the outer Galaxy with a Galactocentric distance ($R_g$) of $\gtrsim$15 kpc, where the metallicity is determined to be as low as $\sim$$-$1 dex. We have obtained near-infrared (NIR) images of young clusters in the outer Galaxy through the 8.2-m Subaru Telescope and have clearly resolved the cluster members with mass detection limits of $\sim$0.1 $M_\odot$. Consequently, we determined that… Expand
