Abstract: |
This paper reviews the contributions made by the BIMA interferometer at Hat Creek to our understanding of the chemical processes in the winds of ABG stars, with particular focus on the formation and destruction of HCN and the related species of cyanopolyynes (HCxN), x = 3, 5, 7, ...). The parallel developments in observations and theoretical models are summarized. Finally, recent work on the origin of HCN in the oxygen-rich (C/O < 1) M giants is discussed. The likely role of pulsationally driven shocks is emphasized. |
