Ap. Ivanov et Vv. Samsonova, The construction of periodic orbits close to triangular libration points for the three-body problem in a resistive medium, J APPL MA R, 64(5), 2000, pp. 751-755
A circular, restricted three-body problem is considered when a passively gr
avitating point also experiences the action of small resistive forces, acti
ng in the opposite direction to the absolute velocity vector. The nature of
the loss of stability of the triangular libration points is studied using
the Poincare method in which the ratio of the magnitude of the resistive fo
rce to the force of gravitational attraction serves as the small parameter.
Asymptotically stable periodic orbits are constructed. Two Lyapunov famili
es of periodic orbits, which exist in the neighbourhood of the libration po
ints of the classical theory, are the generating families. Calculations wer
e carried out for mass ratios corresponding to the Earth-Jupiter and Earth-
Moon systems, with different values of the parameters characterizing the la
w of resistance. (C) 2001 Elsevier Science Ltd. All rights reserved.
