Superheavy stars

   Once the outer layers of stars with mass greater than five sunny, scattered to form the red supergiant, the core due to gravity is beginning to shrink. As compression increases the temperature and density, and begins a new sequence of fusion reactions. Such reactions are synthesized heavy elements that temporarily inhibits the collapse of the nucleus.

   Ultimately, as education increasingly heavy elements of the periodic system, is synthesized from silicon iron-56. Up to this moment of synthesis frees large amounts of energy, but it is the nucleus of iron-56 has a maximum mass of a defect and the formation of heavier nuclei unprofitable. Therefore, when the iron core of the star reaches a certain magnitude, the pressure it is no longer able to resist the enormous force of gravity, and a rapid collapse of the nucleus with neytronizatsiey its substance.

   So what happens in the future, is not clear. But whatever that is, that in a few seconds leads to a supernova explosion of incredible force.

   Accompanying this surge of neutrinos provokes shock wave [source not given 53 days]. Strong jets of neutrinos and the rotating magnetic field is pushed much of the accumulated star material - the so-called rassadochnye elements, including iron and lighter elements. Razletayuschayasya matter scorer is pulling out of the nucleus with neutrons, seizing them, thereby creating a set of elements heavier than iron, including radio, up to uranium (and perhaps even to California). Thus, due to supernova explosions in the interstellar matter of elements heavier than iron.

   Blast wave and a jet neutrinos carry away the material away from the dying star in the interstellar space. Later, moving to outer space, supernova, the material may find other debris, and may participate in the formation of new stars, planets or satellites.
