| Abstract: |
Narrow-band classification photometry, on a six color system that measures near infrared bands of TiO and CN, has been obtained for a set of red supergiants in the Small Magellanic Cloud. To investigate the effects of metallicity on the band strength indices, comparisons are made to supergiants in the LMC and the Galaxy. Two new variable stars are reported. |
