Capture of exocomets and the erosion of the Oort cloud due to stellar encounters in the Galaxy
Joris Hanse, Lucie Jilkova, Simon F. Portegies Zwart +1
The Oort cloud (OC) probably formed more than 4Gyr ago and has been moving with the Sun in the Galaxy since, exposed to external influences, most prominently to the Galactic ti…
The rate of stellar encounters along a migrating orbit of the Sun
C. A. Martínez-Barbosa, L. Jílková, S. Portegies Zwart +1
The frequency of Galactic stellar encounters the Solar system experienced depends on the local density and velocity dispersion along the orbit of the Sun in the Milky Way galaxy. W…
Mass transfer between debris discs during close stellar encounters
Lucie Jilkova, Adrian S. Hamers, Michael Hammer +1
We study mass transfers between debris discs during stellar encounters. We carried out numerical simulations of close flybys of two stars, one of which has a disc of planetesimals…
How Sedna and family were captured in a close encounter with a solar sibling
Lucie Jilkova, Simon Portegies Zwart, Tjibaria Pijloo +1
The discovery of 2012VP113 initiated the debate on the origin of the Sedna family of planetesimals in orbit around the Sun. Sednitos roam the outer regions of the Solar System betw…
The fragility of planetary systems
Simon Portegies Zwart, Lucie Jilkova
We specify the range to which perturbations penetrate a planetesimal system. Such perturbations can originate from massive planets or from encounters with other stars. The latter c…
A debris disk under the influence of a wide planetary mass companion: The system of HD106906
Lucie Jilkova, Simon Portegies Zwart
The 13 Myr old star HD106906 is orbited by a debris disk of at least 0.067 M_Moon with an inner and outer radius of 20 AU and 120 AU, respectively, and by a planet at a distance of…
