Origin of abundance inhomogeneity in globular clusters
Bekki, Kenji; Campbell, S; Lattanzio, John; Norris, John
We numerically investigate abundance properties of the Galactic globular clusters (GCs) by adopting a new 'external pollution' scenario. In this framework, GCs are assumed to originate in forming low-mass dwarfs embedded in dark matter subhaloes at very high redshifts (z) and thus be chemically influenced by field asymptotic giant branch (AGB) stars of the dwarfs during early GC formation processes. GCs within a dwarf galaxy therefore can be formed from the mixture of (i) gas ejected from the...[Show more]
