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…
Evidence of tidal distortions and mass loss from the old open cluster NGC 6791
E. Dalessandro, P. Miocchi, G. Carraro +2
We present the first evidence of clear signatures of tidal distortions in the density distribution of the fascinating open cluster NGC 6791. We used deep and wide-field data obtain…
