WDS 08246-0109 EGN 27 AE : NOTES
| discov_num | notes | refcode |
| B 2527 | FIN measures 1951-1959 distance less than 0.1". | |
| AB pair bound; change in separation and angle consistent with orbital | ||
| motion. B component likely M2-M5 dwarf with mass 0.24 +/- 0.01 Msun. | ||
| C and D components likely unrelated. | Egn2007 | |
| AB: Likely a spurious pair. Last measured 1961 and unresolved by SOAR | ||
| on 3 occasions 2010–2013. | Tok201 | |
| AB: Tentative resolution by Finsen, 1 speckle measure at 0.040" in | ||
| 2001.08, unresolved by Hipparcos, 3 non-resolutions by SOAR 2010-2013. | ||
| AB can be "ghost". | Tok2014d | |
| EGN 27 | AE: E companion was not detected by RoboAO in 2013.05, below limit. | Tok2014d |
