WebAt a planet eccentricity above the planet’s Hill radius divided by its semi-major axis, we find that the disk morphology differs from that exhibited by a disk containing a planet in a circular orbit. An eccentric gap is created with eccentricity that can exceed the planet’s eccentricity and precesses with respect to the planet’s orbit. WebThe square of the orbital period of any planet is proportional to the cube of the semimajor axis of the elliptical orbit. T 2 ∝ r 3 Given that for an object in a circular orbit, the centripetal force on that object is equal to the gravitational force and that speed v = 2 π r /, derive this and find the constant T 2 / r 3.
