Neutron star crust is ten billion times as strong as steel
Thursday, April 16, 2009
From only performed simulations shows that the crust of neutron is over ten billion times as strong as steel, which means that the surface of this very dense objects are strong enough to flatten the star, which arise from the speeds dealing with which maintain and rotate. These gravitational waves produced on our planet may be on the basis of experiments only.
Neutron stars are in fact the cores left over when life is relatively massive stars ending in the form of a supernova. Because the objects in their possession the same mass as the sun and these "packages" is in a sphere of only twenty kilometers in diameter, these objects have an extreme high density. Some of them run several hundred times per second to their axis and this would great waves or ripples in space time created, although it may occur only when the surface of the star is asymmetrical due to the presence of flat parts or different. Material from a nearby star could cause such irregularities. But what is already longer asked is whether the surface of a neutron star is strong enough to withstand the weight of bubbles and such fluctuations.
The crust will normally consist of atoms crystals rich in neutrons. Since experiments in laboratories of the exceptional circumstances on the surface of such stars can not mimic after , astronomers assumed that the crust would be as strong as the strongest substances on earth. The new computer simulations, carried out by Charles Horowitz and Kai Kadau of the Los Alamos National Laboratory, have shown that the crust is much stronger. Materials like rock and steel break easily because they contain small holes, but the enormous pressure in neutron stars would ensure that they are removed and the crystals up ten billion times as strong as steel.
