| 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 |
