| JNN 21 | The primary is an SB2 binary with an 11.8 day period (Torres et al. | |
| 2002 AJ, 123, 1701). Since the angular confirmed to share a common | ||
| proper motion) for the purpose of multiplicity statistics, although it | ||
| is really a triple system. To estimate the mass of the primary for the | ||
| purpose of deriving the mass ratio to the tertiary component detected | ||
| in our images, we adopt the mass ratio of 0.58 derived from the | ||
| spectroscopic orbit and use the mass corresponding to an M3 spectral | ||
| type for the primary. | Jnn2012 |
