The evolutionary stage of the low-temperature contact binary (LTCB) V2388 Oph has been investigated. V2388 Oph was previously
classified as an A-type W UMa star, and is the brighter member of the visual binary Fin 381. When compared to other well-known
LTCBs it is evident that the primary component has evolved to the TAMS, and the companion also seems to be more evolved than
a ZAMS star. Mochnacki proposed a new subgroup of W UMa stars, namely of OO Aql type, distinct from A and W types. V2388 Oph
is suggested to be a member of this new group. 相似文献
