Searching for Pandora
Habitable exomoons appear all over science fiction, but could they exist in real life? Could we detect them if they did?
Could Rings Exist Around Kepler “Warm Saturns”?
Given the possibility that extrasolar planetary rings could be discovered in the Kepler data, this paper investigates what types of ring systems could physically exist around planets with semi-major axes of 1 AU or less. Could rings exist so close to the host star? How might these ring systems look like ones in our own solar system? How would the rings be different? What could a ring detection tell us about the exoplanet?
