| Abstract: |
We have extracted infrared light curves of a small set of evolved stars from the post-cryogen database of the DIRBE instrument on the COBE satellite, extending the cryogenic light curves an additional 2.77 years. These warm-era data have not previously been exploited, although they are of high quality, with median noise levels only about twice that of the cryogenic data. We present some example post-cryogenic light curves, and compare with optical data from the AAVSO and other sources. Wavelength-dependent phase lags, secondary maxima, and cycle-to-cycle variations are visible in these light curves. |
