Currently, there are more than 100 confirmed multiple-planet systems. Moreover, a recent study by Kepler has identified 361 multiple-planet candidate systems. Investigating these systems would give us an important clue in understanding formation and evolution of planetary systems. In such multiple-planet systems, secular interactions among planets could play a significant role in determining th...

[1.01] Asteroids: Radar Observations and Dynamics S. J. Ostro (JPL/Caltech) Radar delay-Doppler measurements are powerful for refining asteroid orbits because they have extremely fine fractional precision and are orthogonal to optical angle astrometry. Radar detection of a newly discovered near-Earth asteroid (NEA) secures its orbit and can add centuries to the interval over which its close Ear...
متن کاملPoincare, Celestial Mechanics, Dynamical-systems Theory and ~chaos~~*
As demonstrated by the success of James Gleick’s recent book [19871,there is considerable interest in the scientific community and among the general public in “chaos” and the “new science” which is supposed to accompany it. However, as usual, it is not easy to separate hyperbole from fact. In an attempt to do this, I will offer a precise definition of chaos in the context of differential equati...

We compare two derivations of a popular formula for the tidal despinning rate, and emphasise that both are strongly limited to the case of a vanishing inclination and a certain (sadly, unrealistic) law of frequency-dependence of the quality factor. One method is based on the MacDonald torque, the other on the Darwin torque. Fortunately, the second approach is general enough to accommodate both ...
