  5. In general, ba stars belong to binary system, and their heavy - element overabundances are due to the accreting material from the companions ( the former tp - agb stars and the present white dwarfs ). carrying out a series of monte - carlo simulations, the changes of orbital elements of binaries are recalculated for wind accretion scenario of the total angular momentum conservation

    研究表明，鋇星應該屬于雙星系統，其重元素超豐來自雙星吸積，它的伴星已經經歷了s -過程核合成，而且由在以前發生的同其伴星（以前是agb星，現已演化為白矮星）的質量傳輸過程中，從伴星那裡獲得了富含重元素的物質，這樣造成了鋇星的重元素超豐。

  10. Our results show that, during the evolution of a binary system, the system widens as it loses mass, and the orbital period increase, while orbital eccentricity remains nearly constant, which can explain the distribution regulation of orbital elements of normal g - k giant and barium stars and the distribution character of the heavy - element abundances of barium stars

    計算結果表明，隨著星風吸積過程的進行，在星風質量損失階段系統軌道半長軸將增大，導致軌道周期增大，而偏心率變化不大，由此可以解釋普通紅巨星雙星系統和鋇星系統的軌道根數的分佈規律和變化情況以及鋇星重元素豐度分佈特徵。
