ups 4 Eri = 41 Eri. Duplicity of AB doubtful.
A is a spectroscopic binary, and possible variable.
HMM 2
Aa1,Aa2: close SB resolved by VLTI. A combined spectroscopic/
interferometric orbit by Hummel et al. (2017) yields component masses
3.17 +/- 0.07 and 3.07 +/- 0.07 Msun, luminosities 100.6 +/- 4.3 and
87.4 +/- 3.3 Lsun, and an orbital parallax of 18.05 +/- 0.17 mas.
