Assume a neutron star has a mass of about 1.2 times the mass of the Sun and a radius of 7 kilometers.

a) Calculate the average density of a neutron star, in kilograms per cubic centimeter.

b) If the escape speed is V2esc=2GM/R, work out the formula for the radius of the Event Horizon around a Black Hole of mass M.

c) Assume the Even Horizon is the size of the Black Hole. What is the density of a Black Hole that has the mass of the Sun?

d) What would be the mass of a Black Hole that has a diameter of 1 cm? Compare it to the mass of Mount Everest (about 5 x 1010 kg).

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

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...

A planet has been discovered around a Sun-like star with an estimated mass of 54.3 times the Earth\'s mass and an estimated radius of 15.1 times the Earth\'s radius. It has been hypothesized that the planet has abundant hydrogen in its atmosphere. In order for the planet to maintain a hydrogen atmosphere for a significant amount of time, the planet\'s temperature must be less than some maximum temperature. Recall that the mass of Earth is 5.97 × 1024 kg and...
