LDS 838 LUY 726-8. L 726-8 = UV Cet. Both components are active flare stars
According to Harrington & Behall the mass ratio is 0.487 +/- 0.011 and
the individual masses are 0.115 (0.008) 0.109 (0.008) Msun for A & B,
respectively. Hrr1973
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
This pm star with flare characteristics is a difficult object. VBs1954
Magnitude uncertain due to flares. USN1988b
AB: Kervella et al. (2016) derive a new orbit for GJ 65 and determine
the following physical parameters:
masses (Msun): A = 0.1225 +- 0.0043 B = 0.1195 +- 0.0043
radii (Rsun): 0.165 +- 0.006 0.159 +- 0.006
[Fe/H] (dex): -0.03 +- 0.20 -0.12 +- 0.20
log (cgs): 5.092 +- 0.015 5.113 +- 0.015 Krv2016
Using the parallax from Gaia DR3 and the mass ratio from Worley, Gai2018
individual masses of Ma = 0.1191 +/- 0.0018 \msun and Mb = 0.1144 +/- Wor1973b
0.0017 \msun are determined for these components. Msn2023
