Stellar evolution and the 'O-rich AGB sequence'
arXiv:astro-ph/0508283
Abstract
The `O-rich AGB sequence' is a well defined area occupied by oxygen-rich AGB stars (OH/IR) in the IRAS two-colour diagram [12]-[25] vs [25]-[60]. This sequence is interpreted in terms of evolutionary stage and/or progenitor mass with the aim to link observed classes of AGB stars and Planetary Nebulae (PNe).
