Frequently, along with debris disks exoplanets have been found to orbit the same central star. These planets influence the dust dynamics by their gravitational potential.
Focusing on secular perturbations, we performed N-body and observational simulations and find that these perturbations can be investigated with spatially resolved images. Furthermore, there appear distinct features in the resolved images which can be used to distinguish between systems with a planet orbiting inward or outward the parent planetesimal belt of the dust.
This can be achieved with a combined observation using JWST/MIRI in Q band tracing the thermal emission of small dust grains and with ALMA at millimeter wavelengths tracing the position of the parent planetesimal belt.
