At the end of its life, a star with a mass 5.8 times the Sun's mass is expected to collapse
At the end of its life, a star with a mass 5.8 times the Sun's mass is expected to collapse, combining its protons and electrons to form a neutron star. Such a star could be thought of as a gigantic atomic nucleus. If a star of mass 5.8 x 1.99 x 1030 kg collapsed into neutrons (mn = 1.67 x 10-27 kg), what would its radius be? Assume that r = r0A1/3.

One of the end stages of stellar life is a neutron star, where matter collapses and electrons combine with protons to form neutrons. Some liken neutron stars to a single gigantic nucleus. Calculate the radius in meters of a neutron star with a mass 2.96 x 1030 kg, treating it as a giant nucleus. Consider the mass of a nucleon 1.675 x 10-27 kg. Your answer should be in the form of N x 104 years. Enter only the number...

Neutron stars are created when giant stars die in supernovas and their remaining cores collapse to a state of immense density where protons and electrons combine to form neutrons. A neutron star is ~1.4 times as massive as the sun and has radius of only ~10 km. For this neutron star compute its escape velocity. What percentage of the speed of light does this correspond to? (Assume for the mass of the sun, M = 1.989 x 10^30 kg).

10. At the end of the Sun’s life it will use up the hydrogen and helium in its core and become a white dwarf. The Sun’s mass is 2.0 × 1030 kg, its radius is 7.0 × 105 km, and it has a rotational period of approximately 28 days. If the Sun should collapse into a white dwarf of radius 3.5 × 103 km, what would its period be if no mass were ejected and a sphere of uniform density...

A neutron star is an extremely dense, rapidly spinning object that results from the collapse of a massive star at the end of its life. A neutron star with 2.3 times the Sun's mass has an essentially uniform density of 4.8× 10^17 kg/m^3. Part A What's its rotational inertia? Assume the star is a solid sphere. Express your answer with the appropriate units. Part B The neutron star's spin rate slowly decreases as a result of torque associated with magnetic...

A neutron star is a star that remains after a supernova, having a large enough density that the it is comprised of mostly neutrons and few protons. A pulsar is a neutron star that spins, radiating electromagnetic energy. We detect this energy as radio waves, noticing that they pulse at a rate of 1 kHz (1000 Hz). Let's assume that this rate corresponds to the rotations per second of the star (1000 rotations per second). Any solid sphere has a...
