Capture of interstellar objects during stellar encounters
Sean N. Raymond, Nathan A. Kaib, Matthew J. Hopkins
As they orbit within the Galaxy, stars swim through a vast population of interstellar objects (ISOs). In this paper, we use N-body simulations to show that a fraction of ISOs withi…
Very-wide-orbit planets from dynamical instabilities during the stellar birth cluster phase
André Izidoro, Sean N. Raymond, Nathan A. Kaib +2
Gas giant planets have been detected on eccentric orbits several hundreds of astronomical units in size around other stars. It has been proposed that even the Sun hosts a wide-orbi…
Impact-induced Vaporization During Accretion of Planetary Bodies
Adrien Saurety, Razvan Caracas, Sean N. Raymond
Giant impacts dominate the late stages of accretion of rocky planets. They contribute to the heating, melting, and sometimes vaporizing of the bodies involved in the impacts. Due t…
On the early thermal processing of planetesimals during and after the giant planet instability
A. Gkotsinas, D. Nesvorny, A. Guilbert-Lepoutre +2
Born as ice-rich planetesimals, cometary nuclei were gravitationally scattered onto their current orbits in the Kuiper Belt and the Oort Cloud during the giant planets' dynamical i…
