Discover inside the star

Physicists working at Argonne National Laboratory (USA) use supercomputers to build a model of the demise of big stars.

Picture 1 of Discover inside the star

The picture illustrates the energy levels in the dying star core. The cooler the color, the greater the energy level.

Picture 2 of Discover inside the star

The last moment of the super-big star before exploding. The energy released by the explosion could be equivalent to 1027 hydrogen bombs, each with 10 million tons of TNT.

The explosion only lasted nearly 5 seconds, but the supercomputer had to mobilize 160,000 processors to simulate it.

Picture 4 of Discover inside the star

The picture above illustrates the three processes of burning the nucleus inside a big explosion. The image of the fire is on the far left. The image in the middle and right illustrates the speed and direction of the fire.

Picture 5 of Discover inside the star

The 3-dimensional image illustrates the giant nuclear flame inside a white dwarf. The buoyancy made the fire move very quickly to the surface of the star to spark the explosion of white dwarfs. Such explosions occur only in the shell - where the material is attracted to - so it does not affect the star core. So they can repeat many times if stars continue to absorb hydrogen gas.

Close-up shots have a high resolution of a nuclear flame inside a white dwarf. It illustrates the complex and chaotic processes within the fire when a white dwarf explosion takes place.
