  Null and timelike equatorial orbits are investigated in a family of hairy
black holes in the cubic Galileon theory. These include rotating
generalizations of static black hole metrics supporting a time-dependent scalar
field. Depending on the coupling and rotation, the properties of the geodesics
expectedly deviate from general relativity. In particular, it is found that
stable circular geodesics only exist below a critical coupling, which is
related to the existence of an outermost stable circular orbit. Focusing on the
strong-field region, images of an accretion disk are also produced to highlight
tendencies that would constrain the model given further accurate observations
of supermassive black holes.
