Researchers previously stated that the super-giant Betelgeuse star is close to exploding, therefore
Later, scientists from the European Southern Observatoryexamined the star and stated that it was back to normal brightness. It turned out that this was not connected with the internal processes of the celestial body; the reason for the tarnishing was a huge cloud of dust that obscured its light. However, researchers from the University of California at Santa Barbara decided to model star explosions using Betelgeuse as an example.
When the core of a massive star endsmaterial, a star collapses under its own gravity and turns into a supernova. Researchers estimate that this is likely to happen to Betelgeuse over the next 100 thousand years. This explosion will create a flash that can briefly eclipse the entire galaxy.
During the simulation of the Betelgeuse explosionthe researchers found that the whole star pulsates in unison, which means that when it dies, it will behave as if it is a static star with a given radius. Therefore, models of supernovae like Betelgeuse are similar to models that do not take pulsation into account.
In other cases, supernova explosions differdepending on the mass of the dying star, the radius and energy of the explosion. Ripples in the stars make it difficult to model an explosion because various layers of the celestial body can expand or contract the explosion: the light from the compact layers of the star is weaker, while the light from the expanding layers is brighter.
