DESTINY: Database for the Effects of STellar encounters on dIsks and plaNetary sYstems
Asmita Bhandare, Susanne Pfalzner

TL;DR
DESTINY is a comprehensive database that models the gravitational effects of stellar fly-bys on disks and planetary systems, covering a wide parameter space to aid research on star cluster environments.
Contribution
It provides the first extensive, publicly available database of stellar fly-by simulations affecting disks and planetary systems across diverse parameters.
Findings
Database covers mass ratios from 0.3 to 50.0
Periastron distances from 30 au to 1000 au
Inclination angles from 0° to 180°
Abstract
Most stars form as part of a stellar group. These young stars are mostly surrounded by a disk from which potentially a planetary system might form. Both, the disk and later on the planetary system, may be affected by the cluster environment due to close fly-bys. The here presented database can be used to determine the gravitational effect of such fly-bys on non-viscous disks and planetary systems. The database contains data for fly-by scenarios spanning mass ratios between the perturber and host star from 0.3 to 50.0, periastron distances from 30 au to 1000 au, orbital inclination from to and angle of periastron of , and . Thus covering a wide parameter space relevant for fly-bys in stellar clusters. The data can either be downloaded to perform one's own diagnostics like for e.g. determining disk size, disk mass, etc. after…
