Chinese name: Eddington limit ； English name: Eddington limit;
Eddington limit is named by Arthur Eddington. Arthur Stanley Eddington Sir Arthur Stanley Eddington (December 28, 1882 November 22, 1944), a British astrophysicist and mathematician, was the first to speak in English relativity Scientists, dense (not hollow) objects in nature Luminous intensity The limit is named "Eddington Limit". The Eddington limit is based on gravitation And radiation pressure balance. The energy generated by the nuclear fusion inside the star is ejected from the inside out. According to the form of energy conversion, part of the heat generated by nuclear fusion is converted into the kinetic energy of atoms after being absorbed by materials. As atoms "struggle" in the core at a very high speed, the speed of atoms in the core of stars can reach thousands or even tens of thousands of kilometers per second.
Therefore, atoms moving at high speed will collide and separate with each other at high speed. In this process, the kinetic energy is converted into gravitational potential energy, that is, the matter will be far away from each other. The kinetic energy of the core will transfer the kinetic energy to the outer layer of the star little by little under the continuous collision and outward impact, making the matter in the outer layer of the star reach the escape speed, and eventually leading to the collapse of the outer layer.
If the mass of the star is too large to exceed the Eddington limit, and the energy rate generated by the core is too large, the heat dissipation rate of the star through light radiation cannot match the energy generation rate, and a large amount of energy accumulated in the core needs to be released, these energies will be transferred from the core to each part of the star through the way of light energy → heat energy, kinetic energy → gravitational potential energy.
Because the final form of conversion is gravitational potential energy, and the form of gravitational potential energy is far away from each other. Therefore, the stars themselves will be far away from each other, making the parts of the stars expand and stretch, and finally the outer structure will collapse completely.
A simple process is equivalent to using a lighter to ignite in a plastic bag. The heat energy pushes the air molecules to fly at a high speed and expand with each other. The plastic bag will be stretched open by the expansion of the internal hot air.
