In order to investigate the plausibility of models which explain all ultraluminous X-ray sources (ULXs) by invoking an intermediate mass black-hole (IMBH) accretor, we have evolved over a hundred thousand binary systems using a full stellar evolution code, using plausible approximations for the dynamical capture of the donor stars by an IMBH in a globular cluster (Madhusudhan, Justham, Nelson, Paxton, Pfahl, Podsiadlowski & Rappaport, ApJ 2006). Our results strongly suggest that, even for favourable assumptions, IMBH cannot be implicated in the majority of observed IMBHs. Hence the Eddington limit is not a strict limit, as is sometimes unjustifiably assumed. We also discuss the need for full stellar evolution codes in simulations of compact binaries in globular clusters, and future prospects for their use in binary population synthesis, particularly in combination with dynamical simulations.
