| Abstract: |
We performed a near-IR/optical monitoring program from 1999 to 2005 in order to study the variability properties of the ‘Arecibo sample of OH/IR stars’ (periods, amplitudes, and color variations). Here we describe this multi-wavelength long-term monitoring program. Data analysis is still in process. Our ultimate goal is to study in particular the oxygen-rich AGB stars with M > 2M⊙, which are probably rare among AGB stars discovered optically and/or in the near-IR, but are common in samples discovered in the mid- to far-IR. |
