THERMAL STRUCTURE OF CONVECTING CARBON-OXYGEN CORES

Date Issued:
1975
Summary:
The evolution of the carbon-oxygen cores of intermediate mass stars immediately prior to and following carbon ignition is described. The thermal consequences of the convectively driven URCA process are considered in detail and applied to these cores following carbon ignition to determine their thermal. We found, as did Paczynski and Ergma, and Couch and Arnett, that a global thermal balance and stability is possible for some models. Unlike the previous investigators, however, we found that some models were possibly unstable due to local heating at the edge of the convective region. The implications for intermediate mass stars burning carbon are potentially serious, as these stars naturally evolve into the region occupied by these unstable models.
