TLDR
The diverse dynamical processes which affect planets, asteroids, comets and pebbles as their parent stars evolve into giant branch, white dwarf and neutron stars are reviewed. Expand
Formation of planetary debris discs around white dwarfs – I. Tidal disruption of an extremely eccentric asteroid
25–50 per cent of all white dwarfs (WDs) host observable and dynamically active remnant planetary systems based on the presence of close-in circumstellar dust and gas and photospheric metalExpand
The great escape: how exoplanets and smaller bodies desert dying stars
Mounting discoveries of extrasolar planets orbiting post-main sequence stars motivate studies aimed at understanding the fate of these planets. In the traditional “adiabatic” approximation, aExpand
THE FORMATION MECHANISM OF GAS GIANTS ON WIDE ORBITS
The recent discoveries of massive planets on ultra-wide orbits of HR 8799 and Fomalhaut present a new challenge for planet formation theorists. Our goal is to figure out which of three giant planetExpand
FORMATION, SURVIVAL, AND DETECTABILITY OF PLANETS BEYOND 100 AU
Direct imaging searches have begun to detect planetary and brown dwarf companions and to place constraints on the presence of giant planets at large separations from their host star. This work helpsExpand
Characterizing the Orbital Eccentricities of Transiting Extrasolar Planets with Photometric Observations
The discovery of over 200 extrasolar planets with the radial velocity (RV) technique has revealed that many giant planets have large eccentricities, in striking contrast with most of the planets inExpand
Outward migration of extrasolar planets to large orbital radii
Observations of structure in circumstellar debris discs provide circumstantial evidence for the presence of massive planets at large (several tens of astronomical units) orbital radii, where theExpand
Planet-Planet Scattering Leads to Tightly Packed Planetary Systems
The known extrasolar multiple-planet systems share a surprising dynamical attribute: they cluster just beyond the Hill stability boundary. Here we show that the planet-planet scattering model, whichExpand
Formation of planetary debris discs around white dwarfs II: Shrinking extremely eccentric collisionless rings
The formation channel of the tens of compact debris discs which orbit white dwarfs (WDs) at a distance of one Solar radius remains unknown. Asteroids that survive the giant branch stellar phasesExpand
One of the closest exoplanet pairs to the 3:2 mean motion resonance: K2-19b and c
Aims. The K2 mission has recently begun to discover new and diverse planetary systems. In December 2014, Campaign 1 data from the mission was released, providing high-precision photometry for similarExpand
