Breaking the Chains: Hot Super-Earth systems from migration and disruption of compact resonant chains
Andre Izidoro, Masahiro Ogihara, Sean N. Raymond +5
"Hot super-Earths" (or "Mini-Neptunes") between 1 and 4 times Earth's size with period shorter than 100 days orbit 30-50\% of Sun-like type stars. Their orbital configuration -- me…
Hot super-Earths and giant planet cores from different migration histories
Christophe Cossou, Sean N. Raymond, Franck Hersant +1
Planetary embryos embedded in gaseous protoplanetary disks undergo Type I orbital migration. Migration can be inward or outward depending on the local disk properties but, in gener…
No universal minimum-mass extrasolar nebula: Evidence against in-situ accretion of systems of hot super-Earths
Sean N. Raymond, Christophe Cossou
It has been proposed that the observed systems of hot super-Earths formed in situ from high-mass disks. By fitting a disk profile to the entire population of Kepler planet candidat…
Making giant planet cores: convergent migration and growth of planetary embryos in non-isothermal discs
Arnaud Pierens, Christophe Cossou, Sean Raymond
Earth-mass bodies are expected to undergo Type I migration directed either inward or outward depending on the thermodynamical state of the protoplanetary disc. Zones of convergent…
Making systems of Super Earths by inward migration of planetary embryos
Christophe Cossou, Sean N. Raymond, Arnaud Pierens
Using N-body simulations with planet-disk interactions, we present a mechanism capable of forming compact systems of hot super Earths such as Kepler 11. Recent studies show that ou…
Convergence zones for Type I migration: an inward shift for multiple planet systems
Christophe Cossou, Sean Raymond, Arnaud Pierens
Earth-mass planets embedded in gaseous protoplanetary disks undergo Type I orbital migration. In radiative disks an additional component of the corotation torque scaling with the e…
Primary and secondary eclipse spectroscopy with JWST: exploring the exoplanet parameter space
A. R. Belu, F. Selsis, J-C. Morales +3
Eclipse exoplanet spectroscopy has yielded detection of H_2O, CH_4, CO_2 and CO in the atmosphere of hot jupiters and neptunes. About 40 large terrestrial planets are announced or…
