The rotation of planets hosting atmospheric tides: from Venus to habitable super-Earths

Mathis, S.; Laskar, J.; Correia, A. C. M. +1 more

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-mass stars. The resulting torque determines the possible equilibrium states of the planet's spin. Here we have computed an analytic expression for the total tidal torque …

Atmospheric tides in Earth-like planets

Mathis, S.; Laskar, J.; Auclair-Desrotour, P.

Context. Atmospheric tides can strongly affect the rotational dynamics of planets. In the family of Earth-like planets, which includes Venus, this physical mechanism coupled with solid tides makes the angular velocity evolve over long timescales and determines the equilibrium configurations of their spin.
Aims: Unlike the solid core, the atmo…

Evaluation of a possible upgrade of the IAU 2006 precession

Liu, J. -C.; Capitaine, N.

Context. The International Astronomical Union (IAU) adopted a new precession model at its 2006 General Assembly. After more than ten years since the publication of the so-called IAU 2006 precession, we have noticed progress in solar system ephemerides and geophysical observations, which can be used to refine the precession model. Another progress …
