What supports a neutron star against the inward pull of its own gravity?
Neutron stars don't collapse and form a black hole because the gravity of the star is balanced by it's outward force. The outward force comes due to neutron degeneracy.
The momentum of a neutron star is more. That puts an outward force over it's gravity and balances them. That's why it doesn't collapse to form a black hole.
What supports a neutron star against the inward pull of its own gravity?
Two identical probes are sent along the same path toward a neutron star. A neutron star is very dense, packing as much as 2 solar masses into a sphere with a radius on the order of 10 km. At the moment shown, the two probes are 57.5 km and 118 km away from the center of the neutron star, respectively. Find the distance between the center of mass of the two probe system and its center of gravity. Number km...
If a neutron star and a white dwarf has a total mass of 1M. If the white dwarf has a radius of 9 x 106 m and the neutron star has a radius of 11 km. i) Compare the surface gravity of both stars. ii) What is the density of the neutron star? iii) Assuming the neutron star is entirely made up of neutrons, and that the interparticle separation of a gas of density n is l = n-1/3. How...
1. (OpenStax 22.10) Gravity always tries to collapse the mass of a star toward its center. What mechanism can oppose this gravitational collapse for a: a) Main sequence star? b) White dwarf? c) Neutron star?
A neutron star has a radius of 10 km, and a temperature of 1 million K. What is its luminosity?
The mass of a certain neutron star is 2.0 x 1030 kg and its radius is 6,000 m (6 km). What is the acceleration of gravity at the surface of this condensed, burned out star? 3.71 x 10 -12 m/s2 2.17 x 1012 m/s2 3.71 x 1012 m/s2 0.53 x 1020 m/s2 5.30 x 1020 m/s2
Neutron stars, such as the one at the center of the Crab Nebula, have about the same mass as our sun but a much smaller diameter.A)If you weigh 670 on the earth, what would be your weight on the surface of a neutron star that has the same mass as our sun and a diameter of 18.0 ?Take the mass of the sun to be = 1.99×1030 , the gravitational constant to be = 6.67×10-11 , and the acceleration due...
What supports a reularstar against gravity? Dark matter. Centripetal forces. Electric/magnetic repulsion. Pressure gradient.
The mass of a certain neutron star is 9 × 1030 kg (4.5 solar masses) and its radius is 5500 m. What is the acceleration of gravity at the surface of this condensed, burned-out star? The value of the universal gravitational constant is 6.67 × 10−11 N · m2 /kg2 . Answer in units of m/s 2 .
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...
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...
