On a Scattered-Disk Origin for the 2003 El61 Collisional Family - an Example of the Importance of Collisions on the Dynamics of Small Bodies
Harold F. Levison, Morbidelli Alessandro, David Vokrouhlicky +1
The recent discovery of the 2003EL61 collisional family in the Kuiper belt (Brown et al., 2007) is surprising because the formation of such a family is a highly improbable event in…
Accretion and destruction of planetesimals in turbulent disks
Shigeru Ida, Tristan Guillot, Alessandro Morbidelli
We study the conditions for collisions between planetesimals to be accretional or disruptive in turbulent disks, through analytical arguments based on fluid dynamical simulations a…
Origin of the Structure of the Kuiper Belt during a Dynamical Instability in the Orbits of Uranus and Neptune
Harold F. Levison, Alessandro Morbidelli, Christa Van Laerhoven +2
We explore the origin and orbital evolution of the Kuiper belt in the framework of a recent model of the dynamical evolution of the giant planets, sometimes known as the Nice model…
Dynamics of the giant planets of the solar system in the gaseous proto-planetary disk and relationship to the current orbital architecture
Alessandro Morbidelli, Kleomenis Tsiganis, Aurelien Crida +2
We study the orbital evolution of the 4 giant planets of our solar system in a gas disk. Our investigation extends the previous works by Masset and Snellgrove (2001) and Morbidelli…
Models of the Collisional Damping Scenario for Ice Giant Planets and Kuiper Belt Formatio
Harold F. Levison, Alessandro Morbidelli
Chiang et al. 2006, hereafter C06 have recently proposed that the observed structure of the Kuiper belt could be the result of a dynamical instability of a system of ~5 primordial…
Accretion of Terrestrial Planets from Oligarchs in a Turbulent Disk
Masahiro Ogihara, Shigeru Ida, Alessandro Morbidelli
We have investigated the final accretion stage of terrestrial planets from Mars-mass protoplanets that formed through oligarchic growth in a disk comparable to the minimum mass sol…
