Stellar and planetary Cassini states
Alexandre C. M. Correia
Cassini states correspond to equilibria of the spin axis of a body when its orbit is perturbed. They were initially described for satellites, but the spin axis of stars and planets…
The Two Rigid Body Interaction using Angular Momentum Theory Formulae
Gwenaël Boué
This work presents an elegant formalism to model the evolution of the full two rigid body problem. The equations of motion, given in a Cartesian coordinate system, are expressed in…
The rotation of planets hosting atmospheric tides: from Venus to habitable super-earths
Pierre Auclair-Desrotour, Jacques Laskar, Stéphane Mathis +1
The competition between the torques induced by solid and thermal tides drives the rotational dynamics of Venus-like planets and super-Earths orbiting in the habitable zone of low-m…
Hayabusa-2 Mission Target Asteroid 162173 Ryugu (1999 JU3): Searching for the Object's Spin-Axis Orientation
T. G. Müller, J. Ďurech, M. Ishiguro +27
The JAXA Hayabusa-2 mission was approved in 2010 and launched on December 3, 2014. The spacecraft will arrive at the near-Earth asteroid 162173 Ryugu in 2018 where it will perform…
Atmospheric tides in Earth-like planets
Pierre Auclair-Desrotour, Jacques Laskar, Stéphane Mathis
Atmospheric tides can strongly affect the rotational dynamics of planets. In the family of Earth-like planets, such as Venus, this physical mechanism coupled with solid tides makes…
Study and application of the resonant secular dynamics beyond Neptune
Melaine Saillenfest, Marc Fouchard, Giacomo Tommei +1
We use a secular representation to describe the long-term dynamics of transneptunian objects in mean-motion resonance with Neptune. The model applied is thoroughly described in Sai…
