STF2909 A: zet 2 Aqr = 55 Aqr A
B: zet 1 Aqr = 55 Aqr B
AB: LDS4971.
EBE 1 The close pair has been resolved by infrared speckle interferometry
(McCarthy 1983). Suspected variability of one of the components is Mcy1983
unconfirmed. Aa,Ab also known as TOK 201.
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
A perturbation of the AB orbit (period ~25y) was first noted by Strand Str1942
(1942). The mass of the third star was subsequently estimated at 0.22
Msun by Harrington (1968) and 0.4 Msun by Heintz (1984). Based on Hrr1968
parallax observations, Franz (1958) associated this third star with Hei1984c
the B component, while Heintz favored the A component. Ebersberger & Fnz1958
Weigelt (1979) found a close visual companion to the A component, Ebe1979
while McCarthy et al. (1982) discovered a companion to B in the near Mcy1982b
infrared. Scardia et al (2010) find the astrometry of the McCarthy Sca2010c
companion to be in good agreement with predictions of the perturbation
orbit, so assume this orbit is associated with B.
