This star was considered unlikely to be a TW Hydra Association member ("N?") by Mamajek (2005; http://adsabs.harvard.edu/abs/2005ApJ...634.1385M ). A detailed astrometric study by Teixeira et al. (2009; http://adsabs.harvard.edu/abs/2009A%26A...503..281T ) found that the star is more likely to be a member of the Beta Pic Moving Group than TW Hydra Association, however TWA membership can not be completely ruled out.
