Scientific paper

We investigate the connection between Asymptotic Giant Branch (AGB) stars, especially OH/IR stars, and planetary nebulae (PN). The latter comprise a mixed population, with a range of spatial and kinematical properties, attributed to the age and mass of the progenitor star. We propose a classification scheme for OH/IR stars based on the separation of the OH peaks and the IRAS (12-25) colour index. It is shown that the OH/IR stars can be separated into classes with spatial and kinematical characteristics resembling those of the corresponding PN types.
