The disk size is fixed at 150 au, and the perturbing star (mass ratio 0.8 relative to the Sun) approaches to within 110 au at periastron, following a 70° inclined orbit with an argument of periastron of 80°. The data can be used for visualising particle properties. The data are openly available via the DESTINY project."],"keywords":["Astronomy and Astrophysics"],"citation":[{"@type":"CreativeWork","text":"Pfalzner, S., Wagner, F. W. & Gibbon, P.
