Just saw this on astrobites.com: Could Rings Exist Around Kepler “Warm Saturns”?

It’s a new paper on arxiv.org that follows a couple of older papers that try to pin down the detectability of rings around exoplanets.  In this case, the authors are focusing only on planets and candidate planets detected by Kepler.  Astrobites does a good job of summing up the paper, so I’ll just provide a couple of other quick-read papers and a book reference if you’re interested in learning more.

Transit Detectability of Ring Systems Around Extrasolar Giant Planets
Detectability of planetary rings around an extrasolar planet from reflected-light photometry
Planetary Rings

This latter reference, a book from the Cambridge Planetary Science series, is a good introduction to (Saturn’s) rings suitable for undergraduates.
