ABSTRACT

In this paper we present several fast integrators and mappings which model the orbital perturbations of Oort cloud comets, caused by the Galactic tide. The perturbations computed with these models are compared with those obtained using an accurate numerical integration using Everhart’s RA15 code. In order to have the best compromise between the computing velocity and precision, it is shown that it is necessary to use a hybrid model i.e. a combination of two algorithms, according to the values of the semimajor axe a and the eccentricity-e of the considered comet.
