| Faramaz et al. (2014): "Can eccentric debris disks be long-lived? A first numerical investigation and application to ζ 2 Reticuli" http://www.aanda.org/articles/aa/abs/2014/03/aa22469-13/aa22469-13.htmlThe binary companion Zeta-1 Reticuli cannot be directly responsible for the eccentricity of the disc around Zeta-2 Reticuli. Suggests that a planet is responsible. - Quote :
- Investigation of the disk structure generated by the scattering processes provided an upper-mass limit of 2 MJup for an outer perturber located in a range of periastra 150–250 AU, whereas a lower-mass limit of 0.1 MJup is associated with inner perturbers in the ζ2 Reticuli system.
