Gravity field and solar component of the precession rate and nutation coefficients of Comet 67P Churyumov-Gerasimenko
Christoph Lhotka, Stefan Reimond, Jean Souchay +1
The aim of this study is first to determine the gravity field of the comet 67P Churyumov-Gerasimenko and second to derive the solar component of the precession rate and nutation co…
Charged dust grain dynamics subject to solar wind, Poynting-Robertson drag, and the interplanetary magnetic field
Christoph Lhotka, Philippe Bourdin, Yasuhito Narita
We investigate the combined effect of solar wind, Poynting-Robertson drag, and the frozen-in interplanetary magnetic field on the motion of charged dust grains in our solar system.…
The effect of Poynting-Robertson drag on the triangular Lagrangian points
Christoph Lhotka, Alessandra Celletti
We investigate the stability of motion close to the Lagrangian equilibrium points L4 and L5 in the framework of the spatial, elliptic, restricted three- body problem, subject to th…
Stability of nearly-integrable systems with dissipation
Alessandra Celletti, Christoph Lhotka
We study the stability of a vector field associated to a nearly-integrable Hamiltonian dynamical system to which a dissipation is added. Such a system is governed by two parameters…
Stability estimates of nearly-integrable systems with dissipation and non-resonant frequency
Alessandra Celletti, Christoph Lhotka
We consider a dissipative vector field which is represented by a nearly-integrable Hamiltonian flow to which a non symplectic force is added, so that the phase space volume is not…
