Pre-main-sequence population in NGC 1893 region

► Support in favour of triggered star formation towards the direction of the two nebulae located at the periphery of the cluster. ► The fraction of disk bearing stars increases towards the periphery of the cluster. ► Evidence in support of the notion that the mechanisms for disk dispersal operate less efficiently for low-mass stars. ► Our result for this region support the claim that the CTTSs and WTTSs are coeval and have indistinguishable properties.
