Earth-like Habitats in Planetary Systems

open access: yes, 2014
Understanding the concept of habitability is related to an evolutionary knowledge of the particular planet-in-question. Additional indications so-called "systemic aspects" of the planetary system as a whole governs a particular planet's claim on ...

Effects of Thermodynamics on the Concurrent Accretion and Migration of Gas Giants in Protoplanetary Disks

open access: yesUniverse
Accretion and migration usually proceed concurrently for giant planet formation in the natal protoplanetary disks. Recent works indicate that the concurrent accretion onto a giant planet imposes significant impact on the planetary migration dynamics in ...

Dynamical architectures of planetary systems induced by orbital migration

open access: yes, 2009
The aim of this talk is to present the most recent advances in establishing plausible planetary system architectures determined by the gravitational tidal interactions between the planets and the disc in which they are embedded during the early epoch of ...

Large Fluctuations within 1 au in Protoplanetary Disks

open access: yesThe Astrophysical Journal
Protoplanetary disks are often assumed to change slowly and smoothly during planet formation. Here, we investigate the time evolution of isolated disks subject to viscosity and a disk wind. The viscosity is assumed to increase rapidly at around 900 K due

Evolution of inclined planets in three-dimensional radiative discs

open access: yes, 2011
While planets in the solar system only have a low inclination with respect to the ecliptic there is mounting evidence that in extrasolar systems the inclination can be very high, at least for close-in planets.

Orbital Migration Through Atmospheric Mass Loss

open access: yesThe Astronomical Journal
Atmospheric mass loss is thought to have strongly shaped the sample of close-in exoplanets. These atmospheres should be lost isotropically, leading to no net migration on the planetary orbit.

Survival of Terrestrial Planets in the Presence of Giant Planet Migration

open access: yes, 2003
The presence of ``Hot Jupiters'', Jovian mass planets with very short orbital periods orbiting nearby main sequence stars, has been proposed to be primarily due to the orbital migration of planets formed in orbits initially much further from the parent ...

Predicting the Dominant Formation Mechanism of Multiplanetary Systems

open access: yesThe Astrophysical Journal Letters
Most, if not all, Sun-like stars host one or more planets, making multiplanetary systems commonplace in our Galaxy. We utilize hundreds of multiplanet simulations to explore the origin of such systems, focusing on their orbital architecture.
