Ye. Abrarova et Av. Karapetyan, STEADY MOTIONS OF A RIGID-BODY IN A CENTRAL GRAVITATIONAL-FIELD, Journal of applied mathematics and mechanics, 58(5), 1994, pp. 825-830
The problem of the two-dimensional translational-rotational motion of
a rigid body in a central gravitational field is considered. All stead
y motions are found, their stability is investigated, and bifurcation
diagrams are constructed. New effects resulting from the use of the ex
act expression for the gravitational potential are discovered.
