Abstract: | Summary Evolution of the orbital elements of a two-body system with slowly decreasing mass according to Jeans' mode is described by a non-linear, non-autonomous system of differential equations.In general the system contains one stationary solution (e=1,f= ), for which an instability criterion is derived. For example the stationary solution is unstable for all Jeans-Eddington functionsm
n
(t) with 1 n 3 which characterize the loss of mass. Furthermore, it is possible to describe the quantitative behaviour ofE+ ,e anda for arbitrarym(t) in a large number of cases. In the case of the Jeans-Eddington functions we find that the amplitude of the oscillations ine is monotone decreasing with time ifn>3 and it is monotone increasing with time ifn<3.By comparing these analytical results with the numerical calculations of Hadjidemetriou we explain the rapid rotation of the line of apsides which occurs if the initial value ofe is nearly-circular.
