Consider a neutron star with a mass equal to 0.9 times the mass of the Sun, a radius of 15 km, and a rotation period of 1.3 s. What is the speed of a point on the equator of this neutron star? What is gg at the surface of this neutron star? A stationary 1.0 kg mass has a weight of 9.8 N on Earth. What would be its weight on the neutron star? How many revolutions per second are made by a satellite orbiting 1.0 km above the surface?

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...

Suppose a star the size of our Sun, but of mass 8.0 times as great, was rotating at a speed of 1.0 revolution every 21 days. If it were to undergo gravitational collapse to a neutron star of radius 20 km, losing three quarters of its mass in the process, what would its rotation speed be? Assume that the star is a uniform sphere at all times and that the lost mass carries off no angular momentum. Answer in rev/day

A typical neutron star may have a mass equal to that of the Sun but a radius of only 12 km. (a) What is the gravitational acceleration at the surface of such a star? (b) How fast would an object be moving if it fell from rest through a distance of 1.5 m on such a star? (Assume the star does not rotate.)

A binary pulsar is a system of two neutron stars of equal mass (each about 1.4 times the mass of the sun and a radius of 10km). A particular binary pulsar has two neutron stars orbiting around their center of mass, and separated by a (center to center) distance of d= 7.0*10^8m. Assume the orbit is circular. a) Calculate the orbital speed of the stars in meters/second. b) Calculate the magnitude of the centripetal acceleration of one of the stars...

Suppose a star the size of our Sun (r=7.0*105 km), but with mass 6.0 times as great, were rotating at a speed of 1.0 revolution every 10 days. If it were to undergo gravitational collapse to a neutron star of radius 10 km, losing 2/3 of its mass in the process, what would its rotation period be in μs? Assume the star is a uniform sphere at all times. Assume also that the thrown-off mass carries off no angular momentum....
