Expansion of the planetary Hamiltonian for small eccentricities and inclinations: a vector formalism
Federico Mogavero
We revisit the classical expansion of the planetary Hamiltonian for small eccentricities and mutual inclinations of the orbits, presenting a derivation based entirely on vector for…
Laplace-Legendre expansion of the planar planetary Hamiltonian
Aya Alnajjarine, Jacques Laskar, Federico Mogavero
We explore a hybrid expansion of the disturbing function in planetary dynamics that combines elements of the classical Laplace and Legendre developments. This formulation retains t…
Numerical approach to second-order canonical perturbation theory in the planetary 3-body problem: Application to exoplanets
Aya Alnajjarine, Federico Mogavero, Jacques Laskar
Extrasolar planetary systems commonly exhibit planets on eccentric orbits, with many systems located near or within mean-motion resonances, showcasing a wide diversity of orbital a…
Timescales of Chaos in the Inner Solar System: Lyapunov Spectrum and Quasi-integrals of Motion
Federico Mogavero, Nam H. Hoang, Jacques Laskar
Numerical integrations of the Solar System reveal a remarkable stability of the orbits of the inner planets over billions of years, in spite of their chaotic variations characteriz…
Long-term instability of the inner Solar System: numerical experiments
Nam H. Hoang, Federico Mogavero, Jacques Laskar
Apart from being chaotic, the inner planets in the Solar System constitute an open system, as they are forced by the regular long-term motion of the outer ones. No integrals of mot…
The origin of chaos in the Solar System through computer algebra
Federico Mogavero, Jacques Laskar
The discovery of the chaotic motion of the planets in the Solar System dates back more than 30 years. Still, no analytical theory has satisfactorily addressed the origin of chaos s…
Chaotic diffusion of the fundamental frequencies in the Solar System
Nam H. Hoang, Federico Mogavero, Jacques Laskar
The long-term variations in the orbit of the Earth govern the insolation on its surface and hence its climate. The use of the astronomical signal, whose imprint has been recovered…
Long-term dynamics of the solar system inner planets
Federico Mogavero, Jacques Laskar
Although the discovery of the chaotic motion of the inner planets in the solar system dates back to more than thirty years ago, the secular chaos of their orbits still dares more a…
Addressing the statistical mechanics of planet orbits in the solar system
Federico Mogavero
The chaotic nature of planet dynamics in the solar system suggests the relevance of a statistical approach to planetary orbits. In such a statistical description, the time-dependen…
Campaign 9 of the Mission: Observational Parameters, Scientific Drivers, and Community Involvement for a Simultaneous Space- and Ground-based Microlensing Survey
Calen B. Henderson, Radosław Poleski, Matthew Penny +118
's Campaign 9 (C9) will conduct a 3.7 deg survey toward the Galactic bulge from 7/April through 1/July of 2016 that will leverage the spatial separation between…
Microlensing planet detection via geosynchronous and low Earth orbit satellites
F. Mogavero, J. P. Beaulieu
Planet detection through microlensing is usually limited by a well-known degeneracy in the Einstein timescale , which prevents mass and distance of the lens to be univocally d…
Models of magnetic-field evolution and effective viscosity in weakly collisional extragalactic plasmas
Federico Mogavero, Alexander A. Schekochihin
In weakly collisional extragalactic plasmas such as the intracluster medium, viscous stress and the rate of change of the magnetic-field strength are proportional to the local pres…
