For this particular study, the researchers used century-old photographic images of Saturn and recent observations made by the Cassini spacecraft to calculate Saturn's Love number - a quantity that, among other things, describes the rigidity of a planet's tidal bulge.
The same effect occurs when a star ventures too close to a black hole, but the pull on the nearside is so much stronger than on the farside that the tidal bulge literally tears the star apart.
Granted that Earth's huge tidal grip has held the lunar rotation 'captive' in spin-orbit synchrony from the earliest times however the lunar orbit may have changed, (3) with the result that there has never been any long-sustained semidiurnal (lunar sense) ebb-&-rise of tides on the Moon, that is, any progressive motion in longitude of the lunar tidal bulge.
2]: the angle between the Earth-Moon line and the axis of the tidal bulge, to obtain the tidal torque ([tau]) on the Moon:
In addition, the same forces give rise to the tidal bulge that is much smaller than the equatorial one (decimeters against kilometers).
With about 10 times the mass of Jupiter (about 3,200 Earths), it's hefty enough and close enough to raise a significant tidal bulge on the star.
ikewise, Miura's team assumes that our planet's mass is raising a tiny but sustained tidal bulge in the sun.
In this configuration, the star's gravity raises a tidal bulge in the planet's atmosphere that sloshes north and south every orbit, injecting heat into the interior that inflates the planet (S&T: February 2006, page 28).
With its close proximity, a parent star will raise a tidal bulge in a hot Jupiter's atmosphere.
Any one planet, acting alone, would tend to distort the surface of the Sun into a prolate spheroid an ellipsoid having one major axis and two equal minor axes with one tidal bulge directed toward the planet and another equal bulge on the side of the Sun away from the planet.
The planet creates a tidal bulge in Europa's crust up to 30 meters high.
