| LPR 2 | Looper et al. (2010) determine NIR spectral types T1+/-1 and T5+/-1. | |
| Distance is estimated at 23pc, separation ~3.9au, orbital period | ||
| 28-35y. Total masses, for ages 0.5, 1.0, and 5.0 Gyr, are 50, 70, and | ||
| 80 Mjup, respectively. Mass ratio is 0.80 +/- 0.9, Teff for A and B = | ||
| 1390 +/- 90 and 1180 +/- 90K. 2MASS component magnitudes are derived | ||
| from their MKO component photometry and spectral type estimates, using | ||
| transformations from Stephens & Leggett (2004 PASP 116, 9). | Lpr2008 |
