Movoj sub newtona logaritma potencialo
A. F. F. Teixeira
Abstract
A linear density of mass is assumed uniformly distributed along an infinitely long straight line. All possible motions of a test particle are described, under the newtonian logarithmic gravitational potential alone. Those most interesting occur in planes normal to the line. An infinity of closed orbits are found, and classified in terms of two positive integers. ----- Maso kun uniforma linia denseco estas ordata sur nefinita rekto. /Gi produktas newtona logaritma potencialo. /Ciu ebla movo de test-parteto estas studata. La plej interesaj movoj okazas en plano normala al linio de maso. Nefinita qvanto de fermaj trajektorioj estas findataj, kaj klasifikataj per du pozitivaj entjeroj.
