JNN 291 | 2MASS J21374019+0137137. This newly discovered binary candidate is a | |
probable member of the bet Pic moving group according to the Schlieder | ||
et al. (2012 AJ 144, 109) study. Its relatively small projected | ||
separation of ∼4.5 au implies that its orbit could be dynamically | ||
constrained in a reasonable timeframe, which makes it a potential | ||
benchmark binary in the future. Estimated age 10-20 Myr; masses 0.11 | ||
+/- 0.04 and 0.05 +/- 0.02 Msun; a ~5.2 au. | Jnn2014 |
