A debris disk under the influence of a wide planetary mass companion: The system of HD106906

The 13-Myr old star HD 106906 is orbited by a debris disc of at least 0.067 MMoon with inner and outer radii of 20 and 120 au, respectively, and by a planet at a distance of 650 au. We use this curious combination of a close low-mass disc and a wide planet to motivate our simulations of this system. We study the parameter space of the initial conditions to quantify the mass loss from the debris di...
