The newest stochastic reputation of these cometary orbits, due mainly to encounters having Jupiter, is examined playing with Lyapunov Trait Evidence
So it matter concerns 9 moments greater than the fresh new estimated people out of energetic J-f comet nuclei
Even if details of the person orbits differ, the 3 comets have very equivalent standard dynamical habits: Its orbits reveal many changes involving the different kinds of resonant activity (satellite and you can anti-satellite librations, and you may stream). For every single comet of your own class, i study brand new influences off initial suggest anomaly, eccentricity and inclination into the stochasticity of orbit. P/Sl and P/Boethin were in past times analyzed. We introduce right here all of our very first outcomes for P/Ge-Wang. Emel’yanenko V. V.* Dynamical Advancement regarding Long-Period Comets and you may Meteor Streams The dynamical development out-of a lot of time-months comets and you may meteor avenues represents making use of the mappings describing planetary perturbations when you look at the an analytical setting for almost-parabolic orbit .
Astron
This new evaluation that have numerical consolidation indicates the favorable efficiency off this method. Brand new formulae that let us to be the cause of personal encounters and you can nongravitational consequences was gotten. A distribution including the Oort cloud try a regular stage regarding this new evolution out of comets during the nearly-parabolic orbits less than planetary perturbations. The general picture of the fresh new progression of your distribution form more w = 1/a good (a great is the semimajor axis) doesn’t are very different somewhat to your first worth of w.Leggi tutto »The newest stochastic reputation of these cometary orbits, due mainly to encounters having Jupiter, is examined playing with Lyapunov Trait Evidence
