Resonant Dust Ring Sculpted by a Super-Earth
A planet twice the mass of Earth shepherds dust near its orbit into a circumstellar ring structure. Both the planet and the dust structure orbit the host star with a period of 5.2 years. Two regions of enhanced dust density lead and trail the planet, which causes periodic localized brightening.

This simulation was computed using NASA GSFC's 420-processor Thunderhead cluster. Stark used the cluster to create a catalog of debris-disk structures caused by Earth-like planets.

The catalog is available at http://asd.gsfc.nasa.gov/Christopher.Stark/catalog.php


This view shows the planet and ring structure from 30 degrees above the planet's orbital plane.    This view shows the planet and ring structure from 30 degrees above the planet's orbital plane.
