Scientific paper

Bolometric magnitudes are obtained for 22 red supergiant variables in the SMC on the basis of infrared photometry. Except for two anomalous objects, these magnitudes fit the period-luminosity relation for massive, core helium burning stars that was previously shown to represent well the red supergiant variables in the Large Magellanic Cloud. In addition, the J-K colors of the LMC and SMC variables are found to be similar.
