Daemgen et al. (2007) derive distance of 19.6 +/- 4.6 pc, separations
of 20.8 +/- 6.0 au (AB) and 3.7 +/- 1.1 au (BC), and predicted orbital
periods of 157 +97/-93 yr (AB) and 16 +10/-9 yr (BC). Spectral types
for the three components are M3.5 +/- 0.5, M4.5 +/- 0.5, and M4.5 +/-
0.5; masses 0.29 +0.11/-0.08, 0.16 +0.05/-0.04, 0.16 +0.05/-0.0 Msun. Dae2007
2MASS J10364483+1521394 is a triple in the Ursa Major moving group,
consisting of a low-mass M dwarf orbited by 2 less-massive companions.
Calissendorff et al. (2017) derive orbits for the BC pair, as well as
A,BC. The semimajor axis for BC is 161 +/- 2 AU; combined mass for the
pair is 0.482 +/- 0.145 Msun. If the BC dynamical mass is constrained
to this value, an orbital solution for A,BC yields a semimajor axis of
38 +/- 4A U and a system mass of 1.00 +/- 0.03 Msun for the triple.
The mass of A is 0.53 +/- 0.20 Msun, while B and C have similar masses
of 0.24 +/- 0.07 Msun each. Jnn2017b
