| Abstract: | To calulate heavy element abundances of barium stars, a new parametric model was proposed in this paper. Based on the model, appropriate fitting parameters and heavy element abundances of 7 barium stars were studied, and nucleosynthesis parameters were discussed. The computing results of heavy element abundances from the model were basically agreeable with these from observations. This means the developed model is valid. |
