The Theoretical Of Planets Oblateness And Its Elationship With The Structure Of The Interiors Of The Planets

Planets oblateness theory is a branch of theoretical astrophysics,we live in the earth is also an object of study for the Earth,which is not only the earth surveying the research object,the theory of geophysical research object.Planets of the flat rate are related not only with its own angular velocity,and other factors,such as their internal structure or the density distribution related to the situation.This paper mainly studies solar system objects rotation in the internal and external gravitational equilibrium shape of the flat rate and stellar internal structure of the flat rate.Planets oblateness theories of solar system objects,the main model are rotating fluids,elastomers and rigid bodies,and also try using the hybrid model of the rigid body or rigid body and fluid and elastomer.Finally,the existing data to verify and compare the derived formula,and as a basis to infer the structure and analysis of stellar structure of the other stars on the planets oblateness.In summary under the guidance of the absorption of previous results and mentor,the paper is divided into the following aspects:First,summed up finishing the celestial shapes and flat rate data,principles and calculation methods.At the same time strengthen the theory of stellar structure,to seek a basis for in-depth study of celestial bodies' flat rate theory.Second,respectively,to explore rotating stars from fluid statics and elasticity on the basis of deformation theory,the derivation of the flat rate formula of rotating planets.And to verify than the basic data of the stars of the solar system,the correctness of the test formula.Third,on the basis of the aforementioned theory to explore the distribution of stellar internal structure with the relationship between the flat rate to more in-depth study of the body's internal structure or the density distribution.Forth,explore the model of the defect and give future research directions and goals,and do further research to improve the theory of stellar flat rate.
