discov_num notes refcode
TOK 301 HIP 76400 is identified by the GCS as an SB2 with a mass ratio q=0.93,
but there is no spectroscopic orbit available. We resolved the 0".19
pair with dI=3.9, indicating a mass ratio of ~0.5 and an orbital
period of ~30yr. Very likely the resolved binary does not match the
spectroscopic double-lined system. Considering the CPM component B at
80" (Tokovinin & Lepine 2012), this system could be a quadruple with a Tok2012c
3-tier "3+1" hierarchy. Tok2015c
Aa1,Aa2 has a period of 368d. Tok2022e
