WSI 121 | Both 2MASS J05100427-2340407 and J05100488-2340148 are binaries in the | |
AstraLux images, so since they are separated by only 27" on the sky | ||
and have very similar proper motions (e.g. Roser et al. 2010), this is | XXX2010 | |
likely a quadruple system in reality. Common proper motion remains to | ||
be confirmed for both of the close components. | Jnn2012 | |
