A long-term numerical solution for the insolation quantities of the Earth
- J. Laskar, P. Robutel, +4 authors B. Levrard
- Physics
- 1 December 2004
We present here a new solution for the astronomical computation of the insolation quantities on Earth spanning from -250 Myr to 250 Myr. This solution has been improved with respect to La93 (Laskar… Expand
Long term evolution and chaotic diffusion of the insolation quantities of Mars
- J. Laskar, A. Correia, M. Gastineau, F. Joutel, B. Levrard, P. Robutel
- Physics
- 1 August 2004
As the obliquity of Mars is strongly chaotic, it is not possible to give a solution for its evolution over more than a few million years. Using the most recent data for the rotational state of Mars,… Expand
An extrasolar planetary system with three Neptune-mass planets
- C. Lovis, M. Mayor, +11 authors Jean-Pierre Sivan
- Physics, Medicine
- Nature
- 18 May 2006
Over the past two years, the search for low-mass extrasolar planets has led to the detection of seven so-called ‘hot Neptunes’ or ‘super-Earths’ around Sun-like stars. These planets have masses 5–20… Expand
Mercury's capture into the 3/2 spin-orbit resonance as a result of its chaotic dynamics
- A. Correia, J. Laskar
- Physics, Medicine
- Nature
- 24 June 2004
Mercury is locked into a 3/2 spin-orbit resonance where it rotates three times on its axis for every two orbits around the sun. The stability of this equilibrium state is well established, but our… Expand
The HARPS search for southern extra-solar planets - XIX. Characterization and dynamics of the GJ 876 planetary system
- A. Correia, J. Couetdic, +11 authors S. Udry
- Physics
- 26 January 2010
Precise radial-velocity measurements for data acquired with the HARPS spectrograph infer that three planets orbit the M4 dwarf star GJ876. In particular, we confirm the existence of planet d, which… Expand
The HARPS search for southern extra-solar planets. VIII. μ Arae , a system with four planets
- F. Pepe, A. Correia, +13 authors S. Udry
- Physics
- 18 August 2006
Context. The µ Arae planetary system is fairly complex, because it contains two already known planets, µ Arae b with P = 640 days and µ Arae c with P = 9.64 days , and a third companion on a wide,… Expand
The HARPS search for southern extra-solar planets - XXVIII. Up to seven planets orbiting HD 10180: probing the architecture of low-mass planetary systems
- C. Lovis, D. S'egransan, +11 authors N. Santos
- Physics
- 23 November 2010
Low-mass extrasolar planets are presently being discovered at an increased pace by radial velocity and transit surveys, which opens a new window on planetary systems. Aims. We are conducting a… Expand
The CORALIE survey for southern extra-solar planets - XIII. A pair of planets around HD 202206 or a circumbinary planet?
- A. Correia, S. Udry, +5 authors N. Santos
- Physics
- 17 November 2004
Long-term precise Doppler measurements with the CORALIE spectrograph reveal the presence of a second planet orbiting the solar-type star HD 202206. The radial-velocity combined fit yields companion… Expand
Deformation and tidal evolution of close-in planets and satellites using a Maxwell viscoelastic rheology
- A. Correia, G. Boúe, J. Laskar, Ádrian Rodríguez
- Physics, Mathematics
- 1 November 2014
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 equation for the… Expand
Dynamical stability analysis of the HD 202206 system and constraints to the planetary orbits
- J. Couetdic, J. Laskar, A. Correia, M. Mayor, S. Udry
- Physics
- 10 November 2009
Context. Long-term, precise Doppler measurements with the CORALIE spectrograph have revealed the presence of two massive companions to the solar-type star HD 202206. Although the three-body fit of… Expand
