| Abstract: |
The Optical Gravitational Lensing Experiment identified over
1,800 carbon-rich Mira and semi-regular variables in the
Small Magellanic Cloud. Multi-epoch infrared photometry
reveals that the semi-regulars and Miras follow different
sequences in color-color space when using colors sensitive to
molecular absorption bands. The dustiest Miras have the
strongest pulsation amplitudes and longest periods. Efforts
to determine bolometric magnitudes reveal possible systematic
errors with published bolometric corrections. |
