Neutron stars are extremely dense objects formed from the remnants of supernova explosions. Many rotate very rapidly. Suppose the mass of a certain spherical neutron star is twice the mass of the Sun and its radius is 6.0 km. Determine the greatest possible angular speed it can have so that the matter at the surface of the star on its equator is just held in orbit by the gravitational force.

Astronomers detect stars that are rotating extremely rapidly, known as neutron stars. A neutron star is believed to form from the inner core of a larder star that collapsed, under its own gravitation, to a star of very small radius and very high density. Before collapse, suppose the ore of such a star is the size of our Sun (R = 7105km)with mass 2.0 times as great as the Sun, and is rotating at a frequency of 1.0 revolution every...

Large stars can explode as they finish burning their nuclear fuel, causing a supernova. The explosion blows away the outer layers of the star. According to Newton’s third law, the forces that push the outer layers away have reaction forces that are inwardly directed on the core of the star. These forces compress the core and can cause the core to undergo a gravitational collapse. The gravitational forces keep pulling all the matter together tighter and tighter, crushing atoms out...

Under some circumstances, a star can collapse into an extremely dense object made mostly of neutrons and called a neutron star. The density of a neutron star is roughly 1014 times as great as that of ordinary solid matter. Suppose we represent the star as a uniform, solid, rigid sphere, both before and after the collapse. The star's initial radius was 9.0×105 km (comparable to our sun); its final radius is 15 km . Part A If the original star...

A star may collapse into an extremely dense body (called neutron star ) composed predominantly of neutrons. This can happen when massive stars die in supernovas and their cores collapse. Represent the star as a uniform solid sphere both before and after the collpase. Assume no astronomical bodies are in the vicinity of the star, so no forces or torques are exerted on the star. The star’s initial radius was 9.45 × 108 m, its final radius is 15200 m,...

Neutron Star Physics Under some circumstances, an ordinary star can undergo gravitational collapse into an extremely dense object made mostly of neutrons. This type of star is called a "neutron star". A neutron star has a mass density roughly 1014 times larger than that of ordinary solid matter. Suppose we represent an ordinary star as a uniform solid rigid sphere, both before and after the collapse. The original star's initial radius is 7.0 x 105 km (comparable to the size...
