Scientists have modeled the explosion of Betelgeuse stars

Scientists from the University of California, having noticed the fading of the Betelgeuse star and deciding that she was dying, began modeling her explosion. Later it turned out that the brightness of the celestial body returned to normal, but the researchers still decided to continue the experiment.

Researchers previously stated that the super-giant star Betelgeuse is close to exploding, so they modeled how the celestial body would look when it began to turn into a supernova. Located in the constellation Orion, it is about a thousand times larger than the Sun, so the energy from its explosion affects the objects around.

Later, scientists from the European Southern Observatory examined the star and stated that it returned to normal brightness. It turned out that this was not connected with the internal processes of the celestial body; the reason for the dimming 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 material ends in the core of a massive star, the 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 explosion, the 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 differ depending 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.
