  The discovery that the centaur (10199) Chariklo possesses a ring system opens
questions about their origin. We here asses the plausibility of different
scenarios for the origin of the observed ring system. We first consider the
possibility that the material of the ring originated in the disruption of a
satellite that had reached a critical distance from the centaur. We discuss the
conditions for the putative satellite to approach the centaur as a consequence
of tidal interaction. A three-body encounter is also considered as a transport
mechanism. In addition, we study the case in which the ring is formed by the
ejecta of a cratering collision on the centaur and we constrain the collision
parameters and the size of the resulting crater of the event. Finally, we
consider that the ring material originates from a catastrophic collision
between a background object and a satellite located at a distance corresponding
to the the current location of the ring. We compute the typical timescales for
these scenarios. We estimate that in order to be tidally disrupted a satellite
would have had to be larger than approximately 6.5 km at the location of the
rings. However the tidal interaction is rather weak for objects of the size of
outer solar system bodies at the ring location, therefore we considered other
more effective mechanisms by which a satellite migt have approached the
centaur. Collisonal scenarios are both physically plausible for the formation,
but semianalytical estimations indicate that the probability of the
corresponding collisions is low under current conditions
