THE OH/IR-PLANETARY NEBULA CONNECTION: SPACE DISTRIBUTION AND KINEMATICS
R. Ortiz, W. J. Maciel
Astron. Astrophys. 287, 552-558 (1994) We investigate the connection between 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.
