Abstract Four core helium flash calculations of varying intensity have been performed. All four flash models mixed residue nuclear species of the core helium flash into and above the hydrogen shell. The peak temperatures for these four flash calculations are 7.4, 8.3, 9.2, and 10.2×108K, the last being about the highest temperature that can be expected without disrupting the entire core. Two other calculations were performed with the recently revised 12C(α,γ)16O rate (Caughlan et al.). The authors focus on the amount and types of nuclear species mixed into and above the hydrogen shell and discuss what surface abundance anomalies the core helium flash can (and cannot) be expected to explain.
