Prompt iron enrichment, two r-process components, and abundances in very metal-poor stars.
WASSERBURG G.J. and QIAN Y.-Z.
Abstract (from CDS):
We present a model to explain the wide range of abundances for heavy r-process elements (mass number A>130) at low [Fe/H]. This model requires rapid star formation and/or an initial population of supermassive stars in the earliest condensed clots of matter in order to provide a prompt or initial Fe inventory. Subsequent Fe and r-process enrichment was provided by two types of supernovae: one producing heavy r-elements with no Fe on a rather short timescale and the other producing light r-elements (A≤130) with Fe on a much longer timescale.
