The analysis of Impact of Earth's figure ellipticity on Its internal structure in imitation of PREM model

The methods of calculation of gravity potential V and potential energy E for ellipsoidal planet for existing one-dimensional mass distribution were not worked out. That’s why now the derivation of formulas for simultaneous calculation of density mass’s distribution and potential and energy for the ellipsoidal body is actual.

The use of Legendre polynomials for the approximation of one-dimensional distributions of planetary mass densities and the study of their convergence

This paper presents investigation of the image's possibility of distribution of lumply-continuous functions with are presented by Legendre polynomials and practical realization of this technique and methods for its improving were investigated.
