Web8 de jun. de 2024 · Star formation is believed to be hierarchical in space and time as a result of turbulence and self-gravity (Scalo 1985; Li et al. 2005; Elmegreen 2010; Kritsuk et al. 2013) within the interstellar medium (ISM). 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
