We find that accretion luminosity delays fragmentation within the halos, but does not prevent it. In halos that slowly form a low number of protostars, the accretion luminosity can reduce the number of fragments that are formed before the protostars start ionising their surroundings. However, halos that rapidly form many protostars become dominated by dynamical p","authors_text":"Paul C. Clark, Ralf S. Klessen, Rowan J. Smith, Simon C. O.
