Very strong instances of these phenomena entrain potentially habitable extrasolar "eyeball planets.
The linearized response of celestial bodies to these phenomena is modeled by the three Love numbers h, k, and l. These phenomena can cause inelastic bodies to gain or lose angular momentum and enter the Cassini state. These phenomena generate resonant ringing oscillations at the periapsis of the orbits of "heartbeat" binary star systems. Very strong instances of these phenomena entrain potentially habitable extrasolar "eyeball planets." Strains caused by these phenomena heat the interior of Europa and cause volcanic activity on Io. The same face of the Moon is always turned towards Earth thanks to "locking" caused by these forces, which also tear apart orbiting bodies that fall inside the Roche ("rohsh") limit. For 10 points, name these forces due to gravitational gradients, which cause sea levels to rise and fall each day on Earth.
