Atmospheric constraints for the CO2 partial pressure on terrestrial planets near the outer edge of the habitable zone
Philip von Paris, J. Lee Grenfell, Pascal Hedelt +3
In recent years, several potentially habitable, probably terrestrial exoplanets and exoplanet candidates have been discovered. The amount of CO2 in their atmosphere is of great imp…
Mini-Oort clouds: Compact isotropic planetesimal clouds from planet-planet scattering
Sean N. Raymond, Philip J. Armitage
Starting from planetary systems with three giant planets and an outer disk of planetesimals, we use dynamical simulations to show how dynamical instabilities can transform planetes…
The impact of atmospheric circulation on the chemistry of the hot Jupiter HD 209458b
M. Agundez, O. Venot, N. Iro +4
We investigate the effects of atmospheric circulation on the chemistry of the hot Jupiter HD 209458b. We use a simplified dynamical model and a robust chemical network, as opposed…
The Compositional Diversity of Extrasolar Terrestrial Planets: II. Migration Simulations
Jade C. Carter-Bond, David P. O'Brien, Sean N. Raymond
Prior work has found that a variety of terrestrial planetary compositions are expected to occur within known extrasolar planetary systems. However, such studies ignored the effects…
Protoplanetary migration in non-isothermal discs with turbulence driven by stochastic forcing
A. Pierens, C. Baruteau, F. Hersant
Low-mass objects embedded in isothermal protoplanetary discs are known to suffer rapid inward Type I migration. In non-isothermal discs, recent work has shown that a decreasing rad…
Building Terrestrial Planets
Alessandro Morbidelli, Jonathan I. Lunine, David P. O`brien +2
This paper reviews our current understanding of terrestrial planets formation. The focus is on computer simulations of the dynamical aspects of the accretion process. Throughout th…
