BAG 50 GJ 1160. Primary is the variable NO UMa. Bag2013
Arenou (2000) gives combined solution of astrometric orbits and DSBs. Are2000
Paper includes masses and distances.
Schlieder et al. (2016) derive the following properties for A and B:
spectral types K2V +/- 0.5 K6.5V +/- 0.5
masses (Msun) 0.83 +/- 0.03 0.65 +/- 0.02
Teff (K) 5020 +/- 50 4150 +/- 30
log (L/Lsun) -0.48 +/- 0.03 -0.96 +/- 0.03. SJE2016
Improved resolved SB2 orbit for this pair. Kie2018
A: Teff = 5105 +/- 21 K, M = 0.834 +/- 0.017 \msun.
B: Teff = 4175 +/- 35 K, M = 0.640 +/- 0.011 \msun.
Orbital parallax = 38.82 +/- 0.23 mas.
Age = 0.4 Gyr.
