An analytical framework for atmospheric tides on rocky planets. I. Formulation
Pierre Auclair-Desrotour, Mohammad Farhat, Gwenaël Boué +1
Atmospheric thermal tides arise from the diurnal contrast in stellar irradiation. They exert a significant influence on the long-term rotational evolution of rocky planets because…
Anisotropic tidal dissipation in misaligned planetary systems
Pierre Auclair-Desrotour, Gwenaël Boué, Baptiste Loire
Tides are the main driving force behind the long-term evolution of planetary systems. The associated energy dissipation and momentum exchanges are commonly described by Love number…
Thermal tides on rocky planets through a novel fully analytical solution
Pierre Auclair-Desrotour, Mohammad Farhat, Gwenaël Boué +2
Thermal tides are atmospheric tides caused by variations in day-night insolation, similar to gravitational tides but with key differences. While both result in delayed mass redistr…
Can one hear supercontinents in the tides of ocean planets?
Pierre Auclair-Desrotour, Mohammad Farhat, Gwenaël Boué +2
Recent observations and theoretical progress made about the history of the Earth-Moon system suggest that tidal dissipation in oceans primarily drives the long term evolution of or…
TOI-4860 b, a short-period giant planet transiting an M3.5 dwarf
J. M. Almenara, X. Bonfils, E. M. Bryant +47
We report the discovery and characterisation of a giant transiting planet orbiting a nearby M3.5V dwarf (d = 80.4 pc, = 15.1 mag, =11.2 mag, R = 0.358 0.015 R$…
Examining the orbital decay targets KELT-9 b, KELT-16 b and WASP-4 b, and the transit-timing variations of HD 97658 b
J. -V. Harre, A. M. S. Smith, S. C. C. Barros +87
Tidal orbital decay is suspected to occur especially for hot Jupiters, with the only observationally confirmed case of this being WASP-12 b. By examining this effect, information o…
Tilting Uranus via the migration of an ancient satellite
Melaine Saillenfest, Zeeve Rogoszinski, Giacomo Lari +4
Context. The 98°-obliquity of Uranus is commonly attributed to giant impacts that occurred at the end of the planetary formation. This picture, however, is not devoid of weaknesses…
The Resonant Tidal Evolution of the Earth-Moon Distance
Mohammad Farhat, Pierre Auclair-Desrotour, Gwenaël Boué +1
Due to tidal interactions in the Earth-Moon system, the spin of the Earth slows down and the Moon drifts away. This recession of the Moon is now measured with great precision, but…
Deformation and tidal evolution of close-in planets and satellites using a Maxwell viscoelastic rheology
Alexandre C. M. Correia, Gwenaël Boué, Jacques Laskar +1
In this paper we present a new approach to tidal theory. Assuming a Maxwell viscoelastic rheology, we compute the instantaneous deformation of celestial bodies using a differential…
Dissipation in planar resonant planetary systems
J. -B. Delisle, J. Laskar, A. C. M. Correia +1
Close-in planetary systems detected by the Kepler mission present an excess of periods ratio that are just slightly larger than some low order resonant values. This feature occurs…
Dynamical analysis and constraints for the HD 196885 system
C. A. Giuppone, M. H. M. Morais, G. Boué +1
The HD\,196885 system is composed of a binary star and a planet orbiting the primary. The orbit of the binary is fully constrained by astrometry, but for the planet the inclination…
Degeneracy in the characterization of non-transiting planets from transit timing variations
Gwenaël Boué, Mahmoudreza Oshagh, Marco Montalto +1
The transit timing variation (TTV) method allows the detection of non-transiting planets through their gravitational perturbations. Since TTVs are strongly enhanced in systems clos…
Tidal dissipation in multi-planet systems and constraints to orbit-fitting
Jacques Laskar, Gwenaël Boué, Alexandre C. M. Correia
We present here in full details the linear secular theory with tidal damping that was used to constraint the fit of the HD10180 planetary system in (Lovis et al. 2011). The theory…
Orbital migration induced by anisotropic evaporation. Can hot Jupiters form hot Neptunes ?
Gwenaël Boué, Pedro Figueira, Alexandre C. M. Correia +1
Short period planets are subject to intense energetic irradiations from their stars. It has been shown that this can lead to significant atmospheric mass-loss and create smaller ma…
