The influence of orbital dynamics, shape and tides on the obliquity of Mercury
Benoit Noyelles, Christoph Lhotka
Earth-based radar observations of the rotational dynamics of Mercury (Margot et al. 2012) combined with the determination of its gravity field by MESSENGER (Smith et al. 2012) give…
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…
The orbit of 2010 TK7. Possible regions of stability for other Earth Trojan asteroids
Rudolf Dvorak, Christoph Lhotka, Liyong Zhou
Recently the first Earth Trojan has been observed (Mainzer et al., ApJ 731) and found to be on an interesting orbit close to the Lagrange point L4 (Connors et al., Nature 475). In…
