. The system consists of a binary pair, designated 41 Arietis A, together with a third companion star, 41 Arietis D. (41 Arietis B and C form optical pairs with A, but are not physically related.) The components of A are themselves designated 41 Arietis Aa (formally named Bharani ) and Ab.

Nomenclature

''41 Arietis'' is the system's

Flamsteed designation A Flamsteed designation is a combination of a number and constellation name that uniquely identifies most naked eye stars in the modern constellations visible from southern England. They are named for John Flamsteed who first used them while co ...

, but is sometimes designated ''c Arietis''. The designations of the two constituents as ''41 Arietis A'' and ''D'', and those of ''A's'' components - ''41 Arietis Aa'' and ''Ab'' - derive from the convention used by the Washington Multiplicity Catalog (WMC) for multiple star systems, and adopted by the
