Reading the Resonant Signatures of Planets in Debris Disks Marc Kuchner Princeton University 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 on a moderately eccentric orbit can create in an optically thin dust disk and compare the resonant geometries found in the solar zodiacal cloud with observations of debris disks around Vega, Epsilon Eridani, and other stars. |
