Various galactic globular clusters display abundance anomalies that affectthe morphology of their colour-magnitude diagrams. In this paper we considerthe possibility of helium enhancement in the anomalous horizontal branch of NGC2808. We examine the dynamics of a self-enrichment scenario in which an initialgeneration of stars with a top-heavy initial mass function enriches theinterstellar medium with helium via the low-velocity ejecta of its asymptoticgiant branch stars. This enriched medium then produces a second generation ofstars which are themselves helium-enriched. We use a direct N-body approach toperform five simulations and conclude that such two-generation clusters areboth possible and would not differ significantly from their single-generationcounterparts on the basis of dynamics. We find, however, that the stellarpopulations of such clusters would differ from single-generation clusters witha standard initial mass function and in particular would be enhanced in whitedwarf stars. We conclude, at least from the standpoint of dynamics, thattwo-generation globular clusters are feasible.Comment: 24 pages, 7 figures, 3 tables. Accepted for publication in Ap
