WDS 19062+3026 STF 2454 AB (HD 178091) : NOTES
 
 
discov_num notes refcode
STF2454 A premature orbit has been computed for AB. Component A reported
double by Dommanget, but observation unconfirmed by observers with
larger instruments. However, A is a SB2, P = 27.25d. From the visual
separations of AB, Baize suspects a third body with P = 35 yr.
A component (suggested as possibly double by Dommanget) perfectly
round on these 3 nights. Baz1954a
Only elements P and T from the orbit of Baize (1976) have been Baz1976
amended by Starikova (1982). Sta1982b
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
