  Chariklo has two narrow and dense rings, C1R and C2R, located at 391 km and
405 km, respectively. In the light of new stellar occultation data, we study
the stability around Chariklo. We also analyse three confinement mechanisms, to
prevent the spreading of the rings, based on shepherd satellites in resonance
with the edges of the rings. This study is made through a set of numerical
simulations and the Poincar\'e surface of section technique. From the numerical
simulation results we verify that, from the current parameters referring to the
shape of Chariklo, the inner edge of the stable region is much closer to
Chariklo than the rings. The Poincar\'e surface of sections allow us to
identify the first kind periodic and quasi-periodic orbits, and also the
resonant islands corresponding to the 1:2, 2:5, and 1:3 resonances. We
construct a map of a versus e space which gives the location and width of the
stable region and the 1:2, 2:5, and 1:3 resonances. We found that the first
kind periodic orbits family can be responsible for a stable region whose
location and size meet that of C1R, for specific values of the ring particles'
eccentricities. However, C2R is located in an unstable region if the width of
the ring is assumed to be about 120 m. After analysing different systems we
propose that the best confinement mechanism is composed of three satellites,
two of them shepherding the inner edge of C1R and the outer edge of C2R, while
the third satellite would be trapped in the 1:3 resonance.
