Massive Star WOH G64 Undergoes Rapid Transformation
WOH G64, a massive star located in the Large Magellanic Cloud, was initially reassessed and confirmed to remain a red supergiant, contradicting earlier beliefs that it was nearing a supernova explosion. Then, astronomers observed unprecedented changes in the star, including a dramatic shift in its color and temperature, which sparked debates about its evolutionary status and future. Subsequently, observations confirmed that WOH G64 is undergoing a rapid transformation from a red supergiant to a yellow hypergiant. This transformation challenges existing models of stellar evolution and provides new insights into the life cycles of massive stars. Researchers have also proposed that WOH G64 may be part of a binary system, which could influence its mass loss and overall evolution. These developments highlight the complexity of massive star evolution in nearby galaxies.
