The Coriolis effect manifests as Rossby waves in the superfluid core of a neutron star. Such waves are "unstable due to gravitational waves," (amazing!) though they are somewhat damped by viscosity. I also read that the Coriolis force dominates in BECs. http://iopscience.iop.org/1367-2630/12/9/093001/pdf/1367-2630_12_9_093001.pdf It also claims that another paper ("Rogue waves as spatial energy concentrators in arrays of nonlinear waveguides" Yuliy V. Bludov, Vladimir V. Konotop, and Nail Akhmediev) shows that this phenomenon is strongly correlated with rogue waves, as seen in the oceans of Earth. Amazing! Unfortunately it costs $40 or so to read that paper, the title seems to have nothing to do with it, and they won't even give an abstract for free. Hmmmph.
