discov_num notes refcode
HJ 4310 AB + TOK 396Aa,Ab: HIP 49442 = HD 88948 is a nearby dwarf in the 3".9
visual binary HJ 4310 AB. According to GCS, the RV of the main
component A varies by 3.5km/s. Here it is resolved into a 0".18 Aa,Ab
pair with an estimated orbital period of 25yr. No astrometric
acceleration was detected, however. The visual secondary B was
targeted separately and found unresolved. Tok2015c
AB: A is SB, no orbit. Tok2014d
