Title:

Reading the Resonant Signatures of Planets in Debris Disks

Abstract:


A planet in a circumstellar dust cloud can carve an easily
visible signature in the dust density via orbital resonances.
This pattern can point to the planet and reveal its orbit
even when the planet itself is much too faint to see. I
will paint an overview of the variety of resonant structures
a single planet can create in an optically thin dust disk, taking
a theoretical perspective. I'll discuss observations of debris
disks with Spitzer, JWST, ALMA, Keck and TPF.
