摘要

We present a new complete expansion of the planetary Hamiltonian function (PHF), with its two components, the indirect and the principal one. The third component is the zero order part, and it has no expansion. In our development the direct and the indirect components are truncated at the third order in planetary masses, but it is manageable to proceed to higher orders. The expansion is achieved, for the first time, using Jacobi-Radau system of origins (Jacobi coordinates). By these coordinates we can attain only one disturbing function (DF) for n planets. A new method to expand Δ_(-s), the mutual distance raised to negative powers, displaying itself in the principal portion is described using symbolic differential operators. The elements Δ~(-s); r r' cos θ and r~(+-m), should be expressed as Poisson series, in terms of the mean anomalies, via eccentric anomalies.
