Will the mysterious star Gemini explode in our lifetime?

Other sudden changes in the behavior of Abt al-Gemini occur regularly, which astronomers believe are caused by the turbulent internal processes of this dying star. One of these changes is revealed in the 2200-day cycle of the star, and astronomers have no explanation for it. Sayo group claimed that this 2,200-day fluctuation is actually the main fluctuation of Abt al-Joza, while the 420-day brightness changes could be its secondary changes. save to Space.com website said:

But in order for Abt al-Juza to be as big as the models, it must be in the last stage of its life. So that its helium fuel is finished and it is burning the carbon obtained from the fusion of helium atoms. If it is determined that this red star is burning helium or carbon, its remaining life can be known. The helium burning phase of a red giant takes at least tens of thousands of years. Once the carbon-burning phase begins, the star has only a few thousand years left to live, at least on a cosmic scale.

While the carbon footprint cannot be precisely determined, evolutionary models suggest that the carbon depletion could occur in less than 300 years, says Sayo. After the carbon depletion, the fusion of heavier elements lasts only a few decades, after which the central part will collapse and the supernova explosion will occur.

Seeing the supernova phenomenon in the sky will be fascinating for terrestrial observers. The last time a bright supernova was seen in the sky was in 1604. Although stars explode daily around the world, many are far away and cannot be seen without powerful telescopes.
