Growing the gas-giant planets by the gradual accumulation of pebbles
Harold F. Levison, Katherine A. Kretke, Martin J. Duncan
It is widely held that the first step in forming the gas giant planets, such as Jupiter and Saturn, is to form solid `cores' of roughly 10 M. Getting the cores to form bef…
Planetary System Disruption by Galactic Perturbations to Wide Binary Stars
Nathan A. Kaib, Sean N. Raymond, Martin Duncan
Nearly half of the exoplanets found within binary star systems reside in very wide binaries with average stellar separations beyond 1,000 AU (1 AU being the Earth-Sun distance), ye…
A Lagrangian Integrator for Planetary Accretion and Dynamics (LIPAD)
Harold F. Levison, Martin J. Duncan, Edward Thommes
We presented the first particle based, Lagrangian code that can follow the collisional/accretional/dynamical evolution of a large number of km-sized planetesimals through the entir…
55 Cancri: A Coplanar Planetary System that is Likely Misaligned with its Star
Nathan A. Kaib, Sean N. Raymond, Martin J. Duncan
Although the 55 Cnc system contains multiple, closely packed planets that are presumably in a coplanar configuration, we use numerical simulations to demonstrate that they are like…
Reassessing the formation of the inner Oort cloud in an embedded star cluster
R. Brasser, M. J. Duncan, H. F. Levison +2
We re-examine the formation of the inner Oort comet cloud while the Sun was in its birth cluster with the aid of numerical simulations. This work is a continuation of an earlier st…
Planetesimal-driven planet migration in the presence of a gas disk
Christopher C. Capobianco, Martin Duncan, Harold F. Levison
We report here on an extension of a previous study by Kirsh et al. (2009) of planetesimal-driven migration using our N-body code SyMBA (Duncan et al., 1998). The previous work focu…
