Super-Puff Exoplanets May Actually Have Huge Ring Systems

Posted: 04 Mar 2020 11:24 AM PST

Super-puffs, an intriguing, growing class of exoplanets, are the objects with exceptionally large radii for their masses and thus correspondingly low densities. According to new research, some of these exoplanets may actually have rings; three super-puffs — Kepler-87c, Kepler-177c and HIP 41378f — are especially good candidates for rings. “We started thinking, what if these […]
