Context. J1407 (
Aims: We test to what degree the ring model of J1407b could survive in an eccentric orbit required to fit the observations.
Methods: We run N-body simulations under the AMUSE framework to test the stability of Hill radius-filling systems where the companion is on an eccentric orbit.
Results: We strongly rule out prograde ring systems and find that a secondary of 60 to 100 MJup with an 11 yr orbital period and retrograde orbiting material can survive for at least 104 orbits and produce eclipses with similar durations as the observed one.
