Explanation Given i. A neutron star is a stellar matter whose density is about that of a nuclear matter – 2 x 10 17 kg/m 3 . ii. The Sun collapses to become such a neutron star without losing any of its present mass. iii. Appendix C for mean density of the Sun = 1410 kg/m 3 , and the mean radius of the Sun = 6.96 x 10 8 m Explanations 1) Concepts Neutron stars are stars that have burnt up all their fuel in fusion of nuclei. It is expected that our Sun will lose all its H into He, then He into C, and so and so forth; because our Sun is a medium-mass star, it is unlikely that Sun will become a neutron star. A neutron stars is a celestial object of very small radius (typically 30 km) and very high density, composed predominantly of closely packed neutrons. Neutron stars are thought to form by the gravitational collapse of the remnant of a massive star after a supernova explosion. 2) Equation i. Density ρ = M/V ii. V α r 3 3) Calculations Since ρ = M/V, and V α r 3 we see that r α ρ -(1/3) Let us say the R S and ρ S – are the current radius and density of the Sun, And R new and ρ S – are the radius and density of the Sun when it becomes a neutron star...

Nuclear Fusion

Nuclear fusion is a type of nuclear reaction. In nuclear fusion, two or more than two lighter atomic nuclei combine to form a heavier nucleus. During this process, an enormous amount of energy is released. This energy is called nuclear energy. Nuclear fu…
