The fresh new stochastic reputation of these cometary orbits, due primarily to encounters that have Jupiter, try investigated using Lyapunov Characteristic Symptoms

For every comet of the category, we research the fresh new impacts regarding initially indicate anomaly, eccentricity and you can desires into the stochasticity of your own orbit. P/Sl and you will P/Boethin was in past times studied. I present here the very first outcomes for P/Ge-Wang. Emel'yanenko V. V.* Dynamical Development out of A lot of time-Months Comets and you will Meteor Streams This new dynamical development from long-period comets and you will meteor streams is known as making use of the mappings explaining planetary perturbations within the an analytical function for any nearly-parabolic orbit .

The brand new analysis that have numerical combination has revealed the favorable overall performance away from this method. Brand new formulae that let me to account for romantic experience and you can nongravitational effects was basically gotten. A shipments including the Oort affect are a routine stage from the fresh development away from comets into the almost-parabolic orbits significantly less than planetary perturbations. The general picture of brand new progression of the distribution function more w = 1/an effective (an effective 's the semimajor axis) cannot will vary significantly to your very first worth of w. Nongravitational forces are very important regions of the brand new transformation of enough time- several months orbits towards the small-several months orbits. With the normal nongravitational pushes, w5-10% of first nearly parabolic comets having perihelion ranges w1 Bien au evolve easily so you're able to orbits which have aphelia in to the Neptunes orbit.
