Abstract
Radio line emission of the HCN molecule has been considered to be a tracer of carbon-rich circumstellar environments1. We report here, however, the detection of HCN radio emission from oxygen-rich late type stars. These results relate to the issue of the progenitors for planetary nebulae2. The presence of the HCN molecule in oxygen-rich stars suggests that complex photochemical reactions are proceeding in the outer circumstellar envelope of late type stars.
