Secular Effects of Tidal Damping in Compact Planetary Systems
Bradley M. S. Hansen, Norman Murray
We describe the long-term evolution of compact systems of terrestrial planets, using a set of simulations that match the statistical properties of the observed exoplanet distributi…
In Situ Models for Planet Assembly around Cool stars
Brad M. S. Hansen
We present a model for the in situ assembly of planetary systems around a 0.5~ star, and compare the resulting statistics to the observed sample of cool Kepler planet ca…
The circulation of dust in protoplanetary discs and the initial conditions of planet formation
Bradley M. S. Hansen
We examine the consequences of a model for the circulation of solids in a protoplanetary nebula in which aerodynamic drag is counterbalanced by the recycling of material to the out…
Eccentric Planets and Stellar Evolution as a Cause of Polluted White Dwarfs
Shane F. N. Frewen, Brad M. S. Hansen
A significant fraction of white dwarfs (WDs) are observed to be polluted with metals despite high surface gravities and short settling times. The current theoretical model for this…
