A period-luminosity relation for supergiant red variables in the Large Magellanic Cloud

Name: Work Video:
Duration: 3 min 30 s
Description: Infrared photometry for 24 red supergiant variables in the LMC is used to derive bolometric magnitudes. The existence of a period–luminosity relation for these stars is demonstrated and compared with theory.
