BUG 17 WISE J072003.20-084651.2 is old, active M9.5 dwarf, distance 6.0 +/-
1.0pc. Companion ~T5, rapidly rotating and magnetically active. Bug2015
Burgasser et al. (2015) derive spectral types M9.5 +/- 0.5 and
T5.5 +/- 0.5. A best-fit orbit based onastrometry and spectroscopy
yields estimated component masses of 0.081 +0.0029/-0.0016 and
0.062 +0.009/-0.011 Msun. T0 was not provided and was determined by Bug2015b
trial and error with comparison to their Figure 8.
Mass : A = 99 +/- 6 \MJup, B = 66 +/- 4 \MJup. Dup2019
Teff : A = 2407 +/- 15 K, B = 1250 +/- 40 K.
