Empirical Constraints on the Oblateness of an Exoplanet
We show that the gas giant exoplanet HD 189733b is less oblate than Saturn, based on Spitzer Space Telescope photometry of seven transits. The observablemanifestations of oblatenesswould have been slight anomalies during the ingress and egress phases, as well as variations in the transit depth due...
