Investigating the disappearance of a massive star in a distant galaxy
A massive star has quietly disappeared in a dwarf galaxy 75 million light-years away, according to a new study. Allan and his colleagues wanted to observe the star to further their research about how massive stars come to an end. Luminous blue variable stars are unstable and can shift in brightness but even then, they leave a traceable calling card for astronomers. "It would be highly unusual for such a massive star to disappear without producing a bright supernova explosion," Allan said. This activity, which contributes to the lack of stability of luminous blue variable stars, can increase their luminosity as well as their rate of mass loss.
