12 Feb 2011: Hashimoto et al. (2011) do not confirm the point source suspected by Oppenheimer et al. (2008). Nevertheless, various gaps and warps in the disk lead to suspect the presence of planets (Hashimoto et al. 2011).
22 Nov 2008: Oppenheimer et al (2008) report this object as "a low significances detection".
