Titanium

Using NuSTAR, scientists will look for clues to the conditions that must be observed in the central part of the exploding star and which show traces of elements in samples scattered throughout the Nebula, left after a supernova explosion. 'You do not have the opportunity to observe the supernova explosions are very common, especially if you choose the bombings, which occurred close enough that they can study in detail' – says Harrison. 'All we can do is study the remnants of supernovae. The composition and distribution of matter in the residues will tell you a lot about the explosion. " We were particularly interested in one element: Ti-44.

The receipt of this Titanium isotope nuclear fusion requires a specific combination of energy level, pressure, and the starting materials. In the depths of a contracting ("collapsing") stars this combination takes place at a depth that is very specific. Anything below this depth, subject to the action of gravity and "collapses" into a subsequent formation of a black hole. Anything above that depth, breaks out into an explosion. Titan-44 is formed just at the point of return (Cusp). Thus, the distribution of titanium-44 throughout the nebula can reveal much about what happened at this critical point in the blast. With this information, scientists can determine what was lost in their computer models.

See title. Some scientists believe that computer models are very symmetrical. Until recently, even having at its disposal powerful supercomputers, scientists were able to simulate only one-dimensional piece of the star.
