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 |
