Webaccretion, infall and merging, and a monolithic scenario, where star formation is rapid and efficient. We distinguish between these modes by defining a characteristic mini-mum mass, M & 1011M⊙, in our fiducial model, for early type galaxies where star formation occurs efficiently. Our results indicate that the hierarchical star formation WebWe perform a study of the spatial and kinematical distribution of young open clusters in the solar neighbourhood, discerning between bound clusters and transient stellar condensations within our sample.
