Ages and Age Spreads in Young Stellar Clusters [SSA]

http://arxiv.org/abs/1709.01736


I review progress towards understanding the time-scales of star and cluster formation and of the absolute ages of young stars. I focus in particular on the areas in which Francesco Palla made highly significant contributions – interpretation of the Hertzsprung-Russell diagrams of young clusters and the role of photospheric lithium as an age diagnostic.
