KOI-1274 B association with KOI-1274 A
Currently the article claims that the secondary star KOI-1274 B is not associated with KOI-1274 A, but the distance of the secondary star in the paper that this statement is referring to, considering its large error range, is consistent with that of the primary, and the low (0.87) certainty of physical unassociatedness in the paper suggests that the companion is likely physically associated with the primary.

 * So about 60% likelihood of being unassociated? Being consistent, within the margins of error, simply means it could be associated, not that it is.  Lithopsian (talk) 13:22, 19 May 2023 (UTC)
