Dynamical Effects of Cometary Bombardment of Saturn’s Rings and Moonss debris are responsible for both physical and dynamical changes in objects orbiting about Saturn. Physical changes include cratering of large bodies and catastrophic disruption of small bodies. Dynamical changes, which are analyzed in this paper, include orbital alteration (principally of ring part作者: Brain-Imaging 時(shí)間: 2025-3-24 10:30

The formation of streams from the breakup of a comet is also discussed. All the evidence, including the recent, discovery of 1983TB points to the correctness of this hypothesis.作者: alliance 時(shí)間: 2025-3-24 23:35

Stellar Perturbations on Cometsy passing stars approaching the Sun at distance less than 1 pc. Within the frame of the impulse approximation we derive analytical expressions for the probability distribution of the impulse imparted to comets for both close and distant approaches. An application to the rate of ejection of comets is presented.作者: 支形吊燈 時(shí)間: 2025-3-29 03:26 作者: Germinate 時(shí)間: 2025-3-29 10:37

The character of their distribution is similar to that of all the known comets.
