In this paper we briefly study changes in the mean seasonal insolations on the planet Mars caused by significant large-scale variations in the following orbital elements: the eccentricity ( e ), the obliquity (ε) and the longitude of perihelion (λ p ). Three orbital configurations have been...
An analytical theory for calculating perturbations of the orbital elements of a satellite due to J2 to accuracy up to fourth power in eccentricity is developed. It is observed that there is significant improvement in all the orbital elements with the present theory over second-order theory. The ...
The masses, m, and the radius, R, of the planet and the satellites are given in Table 1. We also list the mean orbital elements of the major Uranian satellites, obtained by fitting precessing ellipses to the integrated orbits over 1900–2100. The instantaneous position and velocity vectors ...
Since the general perturbations method usually uses mean orbital elements as arguments, while the osculating elements play the role of initial conditions for predictions, the relation between the osculating and mean elements has to be ... E Wnuk - 《Advances in Space Research》 被引量: 7发表: ...

We have developed a semi-analytical theory based on the concept of filtered elements permitting the exact separation between short period and long period variations of the orbital motion. We have studied this concept and the one associated of mean orbital motion in a more comprehensive way than ha...
When expanded to the second order in eccentricity and inclination, the equation can be split into two parts and be used to describe separately the time variation of both orbital elements of a dust grain in a MMR. Dust grains in retrograde orbits in MMRs are also discussed. Numerical ...
We also discuss the possible relationship between the current orbital elements fits of known exoplanets in the 2/1 mean-motion resonance and the expected orbital configuration due to migration. We find that, as long as the orbital decay was sufficiently slow to be approximated by an adiabatic ...
