discov_num notes refcode
STT 358 Alternative spectrum: G2V+G2V
Identification of the ascending node is uncertain due to weak data. Hei1954
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
RED 25 AB,E: M3.5, 35" from G0/F8 binary HD 171746 = HIP 91159 = 2MASS
J18355323+1658316. Proper motion for the brighter star +049-071.
From measurements of DSS POSS and 2MASS plates Reid et al. derive a
proper motion of +080-070 for the M dwarf. Trigonometric parallax
for the G dwarf gives a distance ~34pc, significantly larger than
the spectroscopic distance of 21pc for M star. It is uncertain
whether the stars are associated. Red2007a
AE: 2MASS J18355276+1659057 is possibly a wide companion to HIP 91159 Red2007a
at 35" separation, as noted in Reid et al. (2007). Jnn2012
