Webb9 aug. 2024 · The current epoch of star formation is confined to the Orion A and B molecular clouds, which contain massive clusters such as the Orion Nebula Cluster (ONC), NGC 2024, and NGC 2068. The stars in these clouds have typical ages of ∼1–3 Myr (Levine et al. 2006; Flaherty & Muzerolle 2008; Muench et al. 2008; Da Rio et al. 2010 ). WebbDirect N-body calculations are presented of the formation of Galactic clusters using GasEx, which is a variant of the code Nbody6.
