abstract = "We provide a generalized discussion on the dynamics of a
spacecraft around the equal-mass binary asteroid (90) Antiope,
under the influence of solar radiation pressure at the perihelion
and aphelion distances of the asteroid from the Sun. The
polyhedral shape of the components of this asteroid is used to
accurately model the gravitational field. Five unstable
equilibrium points are determined and classified into two cases
that allow classifying of the motion associated with the target as
always unstable. The dynamical effects of the mass ratio of our
binary system are investigated. We tested massless particles
initially located at the periapsis distance on the equatorial
plane of the primary of our binary asteroid. Bounded orbits around
our system are not found for the longitudes lambda is an element
of {60, 90, 120, 240, 270, 300}. We also discuss the orbital
dynamics in the full potential field of (90) Antiope. The tested
motions are mainly dominated by the binary's gravitational field;
no significant effects of the SRP are detected. For lambda = 180
degrees, less perturbed orbits are identified between 420 and 700
km from the centre of the system, that corresponds to orbits with
Delta a < 30 km and Delta e < 0.15. All the orbits with initial
periapsis distance smaller than 350 km either collide with
components of our asteroid or escape from the system.",
