Direct imaging of an ultracool substellar companion to the exoplanet host star HD 4113A
A. Cheetham, D. Ségransan, S. Peretti +7
Using high-contrast imaging with the SPHERE instrument at the VLT, we report the first images of a cold brown dwarf companion to the exoplanet host star HD4113A. The brown dwarf HD…
The HARPS search for southern extra-solar planets XLII. A system of Earth-mass planets around the nearby M dwarf YZ Ceti
N. Astudillo-Defru, R. F. Díaz, X. Bonfils +13
Exoplanet surveys have shown that systems with multiple low-mass planets on compact orbits are common. Except for few cases, however, the masses of these planets are generally unkn…
Analytical model of multi-planetary resonant chains and constraints on migration scenarios
J. -B. Delisle
Resonant chains are groups of planets for which each pair is in resonance, with an orbital period ratio locked at a rational value (2/1, 3/2, etc.). Such chains naturally form as a…
Spin dynamics of close-in planets exhibiting large TTVs
J. -B. Delisle, A. C. M. Correia, A. Leleu +1
We study the spin evolution of close-in planets in compact multi-planetary systems. The rotation period of these planets is often assumed to be synchronous with the orbital period…
Planets in Mean-Motion Resonances and the System Around HD45364
Alexandre C. M. Correia, Jean-Baptiste Delisle, Jacques Laskar
In some planetary systems, the orbital periods of two of its members present a commensurability, usually known by mean-motion resonance. These resonances greatly enhance the mutual…
