The habitability of Proxima Centauri b II. Possible climates and Observability
Martin Turbet, Jeremy Leconte, Franck Selsis +5
Radial velocity monitoring has found the signature of a ~M planet located within the Habitable Zone (HZ) of Proxima Centauri \citep{Anglada16}. Despite a h…
The habitability of Proxima Centauri b. I. Irradiation, rotation and volatile inventory from formation to the present
Ignasi Ribas, Emeline Bolmont, Franck Selsis +9
Proxima b is a planet with a minimum mass of 1.3 MEarth orbiting within the habitable zone (HZ) of Proxima Centauri, a very low-mass, active star and the Sun's closest neighbor. He…
The Asteroid Belt as a Relic From a Chaotic Early Solar System
Andre Izidoro, Sean N. Raymond, Arnaud Pierens +3
The orbital structure of the asteroid belt holds a record of the Solar System's dynamical history. The current belt only contains Earth masses yet the asteroid…
Migration of accreting planets in radiative discs from dynamical torques
Arnaud Pierens, Sean Raymond
We present the results of hydrodynamical simulations of the orbital evolution of planets undergoing runaway gas accretion in radiative discs. We consider accreting disc models with…
Planet Formation Imager (PFI): science vision and key requirements
Stefan Kraus, John D. Monnier, Michael J. Ireland +75
The Planet Formation Imager (PFI) project aims to provide a strong scientific vision for ground-based optical astronomy beyond the upcoming generation of Extremely Large Telescopes…
Water loss from Earth-sized planets in the habitable zones of ultracool dwarfs: Implications for the planets of TRAPPIST-1
Emeline Bolmont, Franck Selsis, James E. Owen +4
Ultracool dwarfs (UCD; K) cool to settle on the main sequence after 1 Gyr. For brown dwarfs, this cooling never stops. Their habitable zone (HZ) thus s…
