A yellow supergiant (YSG) is a supergiant star of spectral type F or G.[1] These stars usually have masses between 15 and 20 solar masses. These stars, like any other supergiant, are older and swing between blue and red phases depending on the chemical elements they consume in their cores. Until now it had been thought that few supergiants spend a long time in the transitional yellow phase. These systems may be the progenitors of rare supernovae linked to yellow supergiants. Only two such supernovae have been detected - most supergiants go supernova when at the blue (or hot) phase or red (or cool) phase.
