Analytical direct planetary perturbations on the orbital motion of satellites
An analytical expansion of the disturbing function arising from direct planetary perturbations on the motion of satellites is derived. As a Fourier series, it allows the investigation of the secular effects of these direct ...
A frequency approach to identifying asteroid families II. Families interacting with nonlinear secular resonances and low-order mean-motion resonances
(EDP SCIENCES S A, 2009)
Aims. In an earlier paper we introduced a new method for determining asteroid families where families were identified in the proper frequency domain (n, g, g + s) ( where n is the mean-motion, and g and s are the secular ...
Secular dynamics and family identification among highly inclined asteroids in the Euphrosyne region
Among highly inclined asteroids the external region of the main belt beyond the 5J:2A mean-motion resonance with Jupiter has long been known to host the Euphrosyne and Alauda families. The region is confined in semimajor ...
Modelling the secular evolution of migrating planet pairs
The subject of this paper is the secular behaviour of a pair of planets evolving under dissipative forces. In particular, we investigate the case when dissipative forces affect the planetary semimajor axes and the planets ...
The asteroid population in g-type non-linear secular resonances
(Oxford Univ Press, 2017-07-01)
Non-linear secular resonances of g-type, i.e. involving the frequency of precession g of the asteroid pericentre, can affect the proper eccentricities of asteroids in resonant or near-resonant configurations. We first ...
Dynamic portrait of the planetary 2/1 mean-motion resonance - I. Systems with a more massive outer planet
We analyse the global structure of the phase space of the planar planetary 2/1 mean-motion resonance in cases where the outer planet is more massive than its inner companion. Inside the resonant domain, we show the existence ...
A new insight into the Galactic potential: A simple secular model for the evolution of binary systems in the solar neighbourhood
(EDP Sciences, 2017-04)
Context. Among the main effects that the Milky Way exerts in binary systems, the Galactic tide is the only one that is not probabilistic and can be deduced from a potential. Therefore, it is possible to perform an analysis ...
Possible effects of secular resonances in Phobos and Triton
(Elsevier B.V., 2002-01-01)
Due to the tides, the orbits of Phobos and Triton are contracting. While their semi major axes are decreasing, several possibilities of secular resonances involving node, argument of the pericenter and mean motion of the ...
Relating The South Atlantic Anomaly And Geomagnetic Flux Patches

On the first nu(6) anti-aligned librating asteroid family of Tina
Asteroid families are groups of bodies identified in the space of proper elements or of frequencies that share a common origin in the collisional break-up of their progenitors. Their dynamical evolution is shaped by the ...
