Magnetic and tidal migration of close-in planets. Influence of secular evolution on their population
Jérémy Ahuir, Antoine Strugarek, Allan-Sacha Brun +1
Over the last two decades, a large population of close-in planets has been detected around a wide variety of host stars. Such exoplanets are likely to undergo planetary migration t…
Dynamical tide in stellar radiative zones. General formalism and evolution for low-mass stars
J. Ahuir, S. Mathis, L. Amard
[Abridged] Most exoplanets detected so far are close-in planets, which are likely to be affected by tidal dissipation in their host star. To get a complete picture of the evolution…
From Stellar Coronæ to Gyrochronology: a theoretical and observational exploration
Jérémy Ahuir, Allan-Sacha Brun, Antoine Strugarek
Context. Stellar spin-down is the result of a complex process involving rotation, dynamo, wind and magnetism. Multi-wavelength surveys of solar-like stars have revealed the likely…
Could star-planet magnetic interactions lead to planet migration and influence stellar rotation ?
Jérémy Ahuir, Antoine Strugarek, Allan-Sacha Brun +5
The distribution of hot Jupiters, for which star-planet interactions can be significant, questions the evolution of exosystems. We aim to follow the orbital evolution of a planet a…
Exoplanet host-star properties: the active environment of exoplanets
John P. Pye, David Barrado, Rafael A. Garcia +12
The primary objectives of the ExoplANETS-A project are to: establish new knowledge on exoplanet atmospheres; establish new insight on influence of the host star on the planet atmos…
