|Title:||Kirkwood gaps and instability for three body problems|
|Speaker:||Vadim Kaloshin, University of Maryland|
|It is well known that, in the Asteroid Belt, located between the orbits of Mars and Jupiter, the distribution of asteroids has the so-called Kirkwood gaps exactly at mean motion resonances of low order. We study the dynamics of
the Newtonian Sun-Jupiter-Asteroid problem near such resonances. We construct a variety of diffusing orbits which
show a drastic change of the osculating eccentricity of
the asteroid, while the osculating semi-major axis is kept almost constant. We shall also discuss stochastic aspects of dynamics in near mean motion dynamics. This might
be an explanation of presence of Kirkwood gaps.
This is a joint work with J. Fejoz, M. Guardia, and P. Roldan.|
