DDA 2015 – How massive is Saturn's B ring – Clues from cryptic density waves

Matthew M. Hedman (Cornell) Abstract The B ring is the brightest and most opaque of Saturn’s rings, but it is also amongst the least well understood because basic parameters like its surface mass density are still poorly constrained. Elsewhere in … Continue reading
