A neutron star is the remnant left after certain supernovae (explosions of giant stars). Typically, neutron stars are about 18.0 km in diameter and have around the same mass as our sun. What is a typical neutron star density in g/cm3?

A neutron star is the remnant left after certain supernovae (explosions of giant stars). Typically, neutron stars are about 16 km in diameter and have around the same mass as our sun. What is a typical neutron star density in g/cm3? Express your answer using two significant figures.

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...

5) A star (no matter what its mass) spends most of its life Select one: a. as a protostar. b. as a main-sequence star. c. as a planetary nebula. d. as a red giant or supergiant. 6) What is the ultimate fate of an isolated white dwarf? Select one: a. It will cool down and become a cold black dwarf. b. As gravity overwhelms the electron degeneracy pressure, it will explode as a nova. c. As gravity overwhelms the electron...

A neutron star has a radius of 10 km and a mass of 1.4 Solar masses, what is its density and how does this compare to the nuclear density of 2.3 x 1017 kg/m3 (One solar mass is 1.988 x 1030 kg)

2) Densities We discussed White Dwarfs and Neutron stars, very dense objects compared to stars like our sun. On the other hand, we also discussed Red Giants which are much less dense than our sun. To realize just how dense, please compute the average densities (in kg/m) for a) the sun (Rsun=7 x 10 km, Msun= 2 x 1030 kg) b) when the sun becomes a red giant (R= 1AU, M=Msun). By what factor is a Red Giant less dense...

Before leaving Alpha Centauri, you change from the shuttle to a light speed interstellar cruiser and head out deep into the galaxy to visit another binary star system - but this one is composed of dead stars! To occupy your waking travel time by reading about this star system in the "Outer Space Tourbook": Stars spend most of their lifetimes undergoing nuclear fusion in their cores, which is why they give off so much light. However, when the material necessary...

Please solve for Tf and how
fast the neuron star rotate in rotations per seconds.
Formation of a Neutron Star A star rotates with a period of 29 days about an axis through its center. The period is the time interval required for a point on the star's equator to make one complete revolution around the axis of rotation. After the star undergoes a supernova explosion, the stellar core, which had a radlus of 1.5 x 104 km, collapses into...

Chapter 4 Problem 34 A neutron star has a mass of 2.0 × 1030 kg (about the mass of our sun) and a radius of 5.0 × 103 m (about the height of a good-sized mountain). Suppose an object falls from rest near the surface of such a star. How fast would this object be moving after it had fallen a distance of 0.023 m? (Assume that the gravitational force is constant over the distance of the fall and that...

A magnetar is a type of very highly magnetized neutron star. A typical mass is M-2.5Msal, and the radius is thought to about 10km. Assume that the magnetic field B-1015 gauss. 2. Assuming that the magnetar is of approximately uniform density, estimate the total gravitational binding energy. Be sure to get the sign right. Estimate the total magnetic energy. Estimate the magnetic energy density. Express your answer in cgs units. Using Einstein's formula for mass-energy equivalence (E=mc2), express your answer...
