The Relativistic Effect Research Of The White Dwarf,Dark Matter And Neutron Star

The deformed dispersion relation in special theory of relativity is studied in this thesis,the relation of Lorentz breaking and change of the light speed is obtained,and the change of light speed under the action of quantum gravity magnified effect is analyzed.In addition,the relation of radius-mass is calculated according to the modified dispersion relation,Camelia et.al pointed out that it is possible to exist some observation effects for changing of white dwarf radius,but they did not discuss the physical origin of these effects.In this thesis the results show that in the case of the amplification effect or extremely high density,the change of white dwarf radius is obvious.Dark matter is an important research topic in astrophysics and particle physics,a new kind of Q bubble dark matter is studied in this thesis,the energy and radius of Q bubble in stable state are calculated by the modified dispersion relation of energy and momentum,quantum space-time effects on the transition of Q bubble energy level are discussed.In addition,the energy level distribution and particle release of Q bubble are analyzed and compared in the case of perturbation.In the framework of GR and string gravity model,we study the surface temperature distribution for different types of Kerr neutron star,that is,equator/pole temperature ratio of Kerr-Newman-Kasuya,Kerr-Newman-VGM and Kerr-Sen neutron star.In this thesis,we calculate the surface temperature difference of slower rotation and faster neutron star,and analyze and compare the physical law of temperature distribution.The results show that the surface temperature distribution of these Kerr neutron stars is different,and the research of this thesis provides a new idea and method for further astronomical observation.The new work in this thesis is as follows:1.Based on the modified relativistic dispersion relation,the quantum gravity correction of the white dwarf radius is calculated,and the variation of the white dwarf radius of different mass and magnification index is analyzed.2.The energy distribution of the Q-bubble dark matter in the quantum space-time background is studied,the energy level distribution of the Q bubble in the energy correction and the momentum correction is calculated.The Q bubble energy level of perturbation and the particle release are also analyzed.3.The surface temperature distribution of Kerr-type neutron star was studied,the equator/pole temperature difference of K-N-K neutron star,K-N-VGM neutron star and K-Sen neutron star were calculated,and the temperature distribution of different neutron stars was analyzed and compared.
