| discov_num | notes | refcode |
| JNN 25 | 2MASS J03415581-5542287 and J03415608-5542408 are separated by only | |
| 12" and have similar estimated spectroscopic distances (14 and 20 pc, | ||
| respectively) in Riaz et al. (2006), hence it is likely that they form | Ria2006 | |
| a physical pair. 2MASS J03415581-5542287 is a close (~0.61") binary in | ||
| our data, so the system is likely triple in reality, although common | ||
| proper motion of all components has yet to be proven. | Jnn2012 |
