DEA 1 LHS 2803. Deacon et al. (2012) derive Teff 2940 +/- 60 and 1100-120K
for the primary and secondary, respectively. The primary is M4.5 +/-
0.5, the seconary T5.5 +/- 0.5. Distance estimates are consistent with
the pair being physical: 21 +/- 3pc for the primary, 24 +5/-4 pc for
the secondary. Dea2012
Wide M/T binary. Spectral types M4.5 +/- 0.5 and T5.5 +/- 1, masses
0.18 +/- 0.02 and 0.04 +/- 0.01 Msun, age > 4.0 Gyr. Distances for the
two components are consistent, at 21.5 +/- 2.1 and 20.0 +/- 2.0 pc. Muz2012
