discov_num notes refcode
STF1104 A premature orbit has been computed for AB.
AD: Optical pair, based on study of relative motion of the components
using the method of apparent motion parameters. Kiy2008
TOK 391 Ca,Cb: This is another nearby multiple system. The main component HIP
36395 is a visual binary with a known 728yr orbit, also measured here.
The C component (NLTT 17952) at 20".4 is physical, and yet another CPM
component F is found at 1072" (Tokovinin & Lepine 2012), while the WDS Tok2012c
components D and E are optical. We observed C and resolved it at
0".09. The orbital period of Ca,Cb is on the order of 6yr, estimated
masses are 0.6 and 0.4 Msun. We also targeted F and did not resolve
it. The magnitudes and colors of C and F are quite similar. Tok2015c
STF1104 AD: Rectilinear solution by Hurowitz et al. (2013). USN2013a
